Ok a bit more detail. the Sprintex super charger is from an original upgrade fitted by DPR (Dennis Priddle) who did a super charger upgrade to well healed classic range rover 3.9 and 4.2 owners in the 80's /90's. He did do a few 4.6's but that never worked quite so well, Dennis thought the charger was at its limit on the 4.2 and started to lose its performance on the 4.6. I know as i was around at the time when a customer had a 4.2 converted and another customer had a 4.6 conversion, both on range rovers and the 4.2 was the better out of the two. Anyway, i have a couple of these kits, fitted to the pre surpentine V8, with all the various components, which includes a very simple piggy back control modual. This connects to the main engine EFI loom with 4 wires and allows you to increase fuel supply by way of a small screw which is turned by screw driver on front of the box. If you dont add the feuling, you can get pinking under high rpm. Its a basic, but i guess for its time, effective solution, it does work. The idea compression ratio for the conversion was 8.3.1, which is pretty close to the standard 4.2 compression ratio. On his 3.9 conversions, Dennis modified the heads to bring the compression ratio to 8.3.1. On the DPR super charge conversion, the charger is on the dizzy side of the engine, like this not on the top, and just fits in a defender engine bay. I have to say i was really looking for an off the shelf, well proven solution, that's available now. I am also going to use the Compushift, aftermarket setup to control my ZFHP- 24 auto box. So a soulution that works with this would be good. So two different opinions there of mega squirt. Think i'll wait a bit to see if any other members have any thing to add. Thanks for input so far.

I'm putting a 4.2 classic range rover V8 into a new build defender. I have a old V8 loom from the LSE but no ECU. I am thinking of improving the set up with a new engine managment setup, with new loom and ecu etc. Reasons for this are, the old loom is.... well, very old, i would need to get hold of a standard used 4.2 ECU, and they seem to be around £400 on their own off ebay, the existing LSE loom seems to have loads of stuff on it i don't need, like aircon stuff etc. But the main reasons are, i want to be able to add extra fueling as I'm fitting a Sprintex super charger and given that the old system is getting on for 20 years old, i would have thought a new system would be greatly improved, least that's what they all say on the websites, but are they? From what i can see, there are a few to chose from, Mega squirt, Lloyd specialist V8 people, RPI engineering. Anybody got any experience with any of these or others? I could always use the old LSE system and and just figure out how the piggy back sprintex ecu, fits into the LSE engine loom? Oh and i'm not mud bathing in this one, so the waterproof side doesn't matter really.

Thanks for that Raife, probably saved me a lot of time searching for the part number. Seems odd that its not avaible? Oh well better start looking for the "slug"!.

Does anyone out there have or have the part number for the shoe / mounting peg / bracket, the bit that sticks onto the windscreen, for the range rover classic anti glare control rear view mirror, like this one on ebay 153220023945 ? I have a mirror, but need the shoe and i can not find the part number of one anywhere.

Ok, new to this site and had'nt noticed there were seperate forums for defenders and range rovers etc, know now. This is proving to be difficult, looked at all those links and cant find anything in the search or index, that match's windscreen, let alone "rear view mirror windscreen mount". is it under Body or interior trim or what?

Does anyone out there have or have the part number for the shoe ( i think thats what you call the bit that sticks onto the winscreen?) for the range rover classic anti glare control rear view mirrow, like this one on ebay 153220023945 ? I have a mirror, but need the shoe. Thanks John

Looked over the forum and cant find one, anyone know where i can access one?

Evening all. Can anybody help me with getting the land rover wiring diagrams for defenders / discoveries etc. I have just spend 1.5 hours of wasted time trying to find , open , down load any and still not got anywhere. I tried the links on a previous thread to down load Rave files. I've done that twice now , but cant find for the life of me any wiring or anything that will open. My pc keeps saying PDF cant be opened? Is it me or the files? I am tryinmg to find some wiring diagrams for 300defender tdi engine loom, disco l and ll auto box loom, classic range rover loom amoungst other things. Got a headack now!

no classic had a cable going to the chassis mounted transducer. i actually found all the plugs on my loom in the end. I dident look at the engine part loom ,which is a 300tdi and it turns out this goes all the way back to drivers seat box and passes the gear box on the way. As i am building this from parts and never took it apart, only much older 90's, its amazing how long these stupid little things can take.

yep thats the great, thanks

I am looking for NAS style rear step for a defender 90 with detachable tow hitch, anybody seen this around or know if this is available anywhere?

Ahh, that helps a lot. I can see that the main loom runs over the top of the gearbox and into the drivers seat box. i thought it ran around the edge of the chassis, as i havent actuall offered it up yet. So my speed tranducer and reverse switch might be on the main loom, where i was'nt expecting or looking for it, i'll look later. Thanks for pic. I'm near Bristol, south west, where are you? So is your HP22E mated to a TD5 diesel?

Ok just did some digging around, and the system looks great and had i have know about this before i installed my stage 3 Ashcroft HP22 (not HP22E) I would have gone for the electronic version. I avoided it as i thought the electronics in a custom vehicle would be a night mare. But i guess a lots changed in 10 years. So back to my problem, where are the connections?

So is yours a HP22 E from a disco?

Ok i will look at Compushift, never heard of it. So you can recormend this V8 Freak? I was also thinking of ditching the LSE engine loom and ECU i have and going for an updated, tunable engine managment system as well, any experience of that?

Ok next wiring conundrum, gearbox loom, of lack of it! Quick recap, defender build, based on TD5 around 2004 mark, rover V8 EFI 3.9. auto I have a ROW TD5 loom (no ECU), basic. YMC002383. I have a TD5 chassis loom, can’t (find a part number on that) but it had a 4 wire rear tank fuel pump / sender connection and orange bulk head plug TD5 lamp connectors etc. I have all the other loom parts, wings, instruments etc. So I have this on a bench and have plugged everything in, and I’m pretty sure (checked 5 times) I have used all the plugs, so in theory everything is on. My next step was to mate the ZF HP22 auto box loom to the main loom. This is from a classic range rover and I have the gearbox loom to match. I was expecting to find an unused plug in my loom somewhere, which was the gear box loom connector, but there are no connections for this on the main loom or chassis loom. I assumed all defenders had a gear box loom that plugged into the main loom, with the variations for different models? I realise that this HP22 auto box was only fitted to the 50th anniversary by land rover and that loom might be a one off and that I would have to make some modifications to the loom. But I was expecting to find the connections all the gearboxes use, i.e. speed sensor, reverse gear, diff lock etc., either off the chassis loom or off the main loom via a plug. So where is it? My only thought at the moment is that my chassis loom is not matched to the main loom and that, sometimes the gearbox has its own loom and plugs into the main loom and sometimes it comes off the chassis loom directly and I have ended up with a mis matched pair and have neither? My plan was to find a discovery 2 auto box loom as it’s the same gearbox similar year and work out how to connect it to the TD5 loom, but without any starting point, I’m a bit stumped? That does bring me to another point, is there anywhere I can get the Rave stuff so I can look all the wiring from different models, to work this stuff out? I am doing it via Google images at the moment and it takes for ever to find the correct pages as they seem to be mis titled most of the time, plus there is a company who want me to part with my credit card details to view the pages, which I’m not too keen on for scamming reason. When I started this 7 years ago, (no, I’m not that slow, its was taken over by life’s little challenges for 6 years!) I had the Rave stuff in full but now I can’t find it.

Does anyone out there have or have the part number for the shoe ( i think thats what you call the bit that sticks onto the winscreen?) for the range rover classic glare control rear view mirrow, like this one on ebay 153220023945 ? I have a mirror, but need the shoe.

Update, for anyone else trying to do this. Whilst trawling back through old copies of L/R mags, i found an article in LRM july 2013 (see it does pay to keep all those old copies, tell the wife!) Defender ABS Retro fit. Fitting a TD5 ABS to a ROW (Rest of world) TD5 loom, which is what i have. Anyway, wont bore you all with detail, but it was done and sucessfull, by IRB developments. I just have to beaver away and find out some of these last few wiring details as the article was not that in depth. I also have to work out how to wire in a OBD2 diagnostic socket as i had not thought about the fact that i way need to do some diagnostics or at least reset the ABS ECU.

Very interesting read Keeley75, a lot of my niggling little things to work out, i got from your very detailed build, thanks. I'm also trying to do a similar " as factory as possible" build. One thing i dident see, maybe you can help. As you can tell i am at the figuring out how to mate all the different wiring up. I too have fitted a ZF HP22 auto box, but mine from a classic range rover. I have the gearbox loom, but it has all the older type R/R plugs etc. Did your disco HP22 loom have later plugs and did it plug straight into your loom? Do you have any info on this? Thanks John

Very usefull, thank you Dailysleaze and to all other inputs.

Hi I've fitted a ZF 4HP22. auto box to my TD5 2006 defender build, with V8 and am now looking at the gearbox oil cooler. I have a good classic range rover gearbox oil cooler, the tube type with fins, fitting each end. Does anyone know if the classic range rover gear box oil cooler pipes are the right length and will fit? Its a classic rangy gearbox and oil cooler, so threads should be ok, its just the length i am worried about before i buy some? Or any other advice / suggestions?

In hinds sight it would have been better to get an ABS 300tdi loom and strip the ABS stuff out of that in stead of a TD5 ABS loom. Oh well:)

Yes i have traced, through wiring diagrams, the one that goes to the speedo, i think the yellow / pink from memory, but will check. So i am thinking that on the 300 TDi, it takes its speed from the speedo rather than the engine ECU, as on later TD5's My loom is in fact a 2006 defender, but i think they call it third world issue, not available in UK or europe. In effect its a 300tdi loom, (no ecu) but with the later TD5 connectors etc. I did not want the hassle of trying to make an ECU work with my V8 conversion, been there before on another project, so plumped for the none ecu loom. Anyway, going off track now. So i guess the ABS ECU needs the throttle position and speed for traction control, not braking, as you would not be excellerating and braking at the same time. Interesting, a bit more research i think. Thanks all.

Before we start, i am retro fitting ABS to a defender, chassis up build, so don't try and persueded me not to, its too late, 95% of the way there. Ok, i have late TD5 ABS axel's, the actuator, all plumbed in. I have the ABS loom from a TD5 defender, with ECU and so far, worked out all the wiring, dash lights, loom etc etc. But i am fitting this to a 300tdi loom, ie no ECU, and because of this i cant connect one wire, the wire that goes from the ABS loom to the TD5 ECU. Does anyone know what purpose this wire has , and if the ABS will work with out it connected? The wiring diagram does not seem clear on what this wire does, feed information to the Main ECU for control of engine speed / diagnostics or feed information from the main ECU to the braking ECU, or something else? One other question, obviously i am very aware that this is braking and vital it works properly. But i have been told that as a saftey feature, Land rover designed this, that if ABS electrics should fail, the brakes revert back to working as none ABS braking, and therefor no worse that having none ABS brakes in the first place. I'm not using this to short cut the job, just interested if this is true. Can anyone confirm this from facts, not assumptions? Any body go an answer to the wire or point me in the direction of any usefull acticles on this? Thanks Johnny
