tolley Posted November 3, 2016 Share Posted November 3, 2016 can anyone tell what these wire might be for , got the disco a few weeks back and found some diy wiring . seems to be coming from the green box passenger side , yellow wire has been joined to the blue /brown and just behind that yellow joined to grey and then above black to green/white and black/white will have to check colours .

BogMonster Posted November 3, 2016 Share Posted November 3, 2016 Some sort of bodge for the immobiliser would be my guess. You need a workshop manual and wiring diagram to work out what those wires do. The green box is the 10AS alarm ECU. Quote Link to comment Share on other sites More sharing options...
BogMonster Posted November 3, 2016 Share Posted November 3, 2016 It might be helpful to post what works and what doesn't in that system (anything relating to alarm, immobiliser, central locking, remote locking fobs) Quote Link to comment Share on other sites More sharing options...
tolley Posted November 4, 2016 Author Share Posted November 4, 2016 central locking works , remote works ,will have a look later at the rest , any thing I can do to sort it out please advise . hate to think what else I might find thanks for replying Bogmaster Quote Link to comment Share on other sites More sharing options...

BogMonster Posted November 5, 2016 Share Posted November 5, 2016 You need to unlock with the fob on that age of vehicle, that or the EKA code are the only way to disarm the alarm. You cannot do so just by opening it with the key, even if you locked it with the key you must use the fob to open it. Quote Link to comment Share on other sites More sharing options...
teabag Posted November 5, 2016 Share Posted November 5, 2016 Lock with fob or key to isolate the ultrasonic movement detector, but only unlock with the fob. Unlocking with the key will set off the alarm. I have the wiring diagrams in my Haynes work shop manual, so either get your self the manual or download from the www LRs mechanical and electrical manuals called RAVE, but the don't show wiring in the the security system as u would expect.

Peaklander Posted November 5, 2016 Share Posted November 5, 2016 (edited) I can't see the exact connections into the grey plug but those two on the green are the link into the indicator circuit to allow the flash(es) when you arm and disarm. If you can be more specific with the wires into the green connector I will be able to see what they are. The colours seem to change as your eye follows the wires - at least on my screen.

teabag Posted November 6, 2016 Share Posted November 6, 2016 (edited) No not just the alarm on its own. Powering down the security system and the ECU will remove the alarm plus the immobiliser which if it isn't already bypassed you will have to install the now missing two circuits that were used to immobilise the engine, you will also lose the central locking function. But it that's on an unmolested system, sort out that wiring first to understand why it's has be altered.

tolley Posted November 6, 2016 Author Share Posted November 6, 2016 ok , don't mine not having the alarm , immobiliser , central locking . is it the fix bridging 2 wire and removing the green box ? Quote Link to comment Share on other sites More sharing options...
Peaklander Posted November 6, 2016 Share Posted November 6, 2016 I agree with that. Your interior lights probably don't work unless the bodge has 'fixed' that. They should go on when the alarm is unset and give you an off delay when you set it. My Defender was similarly bodged when I bought it. You need a bit of patience but it is possible to follow the wires and see what's what. You would need to search online for the manuals but they are there. You can get the connections to the 10AS unit ( the green one you mentioned which is the alarm 'ecu'), another shows the configuration of the two connectors so you can confirm the wire colours on the wiring diagram and there's also stuff that explains how to re-sync the fobs. You also don't necessarily need any plugin computer to get it working, at least I didn't. Quote Link to comment Share on other sites More sharing options...

That's all it is, ignition switched supplies, one to the starter motor or maybe the relay, the other is to the fuel pump or whatever ever a Diesel has in the engine bay that the two items that the immobiliser isolates, so no that difficult to do, an hour or so if you wish to be neat in that way you install the additional wiring. Pull the fuses and power down the security ECU (green box) and leave it in situ, job done. And if you really mis the central locking you can aways install a aftermarket central locking ECU. In the mean time pull the fuse or unplug the ECU and see what happens. Edited November 6, 2016 by teabag Quote Link to comment Share on other sites More sharing options...

tolley Posted November 14, 2016 Author Share Posted November 14, 2016 ANYONE GOT A COLOUR WIRING DIAGRAM ,(FOUND A DEFENDER IF ITS THE SAME ) I HAVE THE RAVE CD ,BUT CAN'T FIND WIRING Quote Link to comment Share on other sites More sharing options...
BogMonster Posted November 15, 2016 Share Posted November 15, 2016 If you have the rave CD look for electrical troubleshooting manuals. I think they are in there. Older LR wiring diagrams are really not very good. Quote Link to comment Share on other sites More sharing options...
Peaklander Posted November 15, 2016 Share Posted November 15, 2016 Google is a wonderful thing. Have you tried searching for Defender wiring diagram? If you do you will find this link easily that is going to show you how the AS10 interfaces with the looms and if the wire colours in those diagrams match your Disco then bingo! There's loads of stuff here too including plenty about the alarm system There's a manual called defender electrical library which shows the wires and their position in the connectors. Again, for the AS10 I would assume these are the same on your Disco but just google and download it and make the comparison. Quote Link to comment Share on other sites More sharing options...
