Darren Posted January 24, 2008 Share Posted January 24, 2008 Can anybody help put a date on the instruments in my 110? Whilst the truck is, on paper, a 1987/E reg, it's been extensively re-built at some point, I think by Frogs Island 4x4, and many of the body panels and other fittings are from later vehicles - the rear axle is also a later disk braked version. Anyway, whilst fiddling with the wiring to the back of the instruments I managed to get an engine check light to light up on the warning light pack. I know the original 2.5TD would never have had such a thing so I'm guessing either late 300tdi or TD5? Looking at the rather worn state of the bezel, I think the speedo is the original, but the fuel and temp guage look much newer. The fuel gauge also has no damping on the reading, bouncing backwards and forwards when the vehicle is moving. The gauge on the right is a VDO oil pressure gauge. Any help would be appreciated. When I bought it I knew the wiring was going to be a bit of a challenge as several things didn't work (including the fuel gauge) as they hadn't been connected. However, the more I look, the bigger the challenge becomes. It seems that the whole vehicle has been re-wired from scratch with many relays mounted on what look like purpose made PCB's. There are three of these in a large waterproof box under the bonnet and one each in the rear light clusters, with each bulb having it's own relay and fuse!

sgnas Posted January 24, 2008 Share Posted January 24, 2008 Looks like a TD5 "pod", with the old speedo head in. Quote Link to comment Share on other sites More sharing options...
western Posted January 24, 2008 Share Posted January 24, 2008 Definitly the old speedo [original] just like mine & the rest is Td5 stuff, read the 'wibbly wobbly speedo' thread in the defender forum on how to fit the Td5 speedo, I've got the bits ready to fit in my '89 110 Quote Link to comment Share on other sites More sharing options...
Darren Posted January 24, 2008 Author Share Posted January 24, 2008 Thanks chaps. Anybody know where I can get a wiring diagram for the TD5 instrument pack? To be honest, most of it seems to work as it should do. It'd just be nice to know what I'm looking at and also see if there's anything currently unused that I might be able to make use of. I'll file the info on the TD5 speedo for future reference, thanks. I've got enough wiring to sort out as it is without adding to it at the moment Is there any obvious way of identifying a TD5 bulkhead? I'm pretty certain the bulkhead has been replaced but it'd be nice to be able to confirm it. Quote Link to comment Share on other sites More sharing options...
western Posted January 24, 2008 Share Posted January 24, 2008 This .jpeg files might help, extracted from the Td5 1999 workshop manual wiring info. Quote Link to comment Share on other sites More sharing options...
Mo Murphy Posted January 24, 2008 Share Posted January 24, 2008 Darren, The fuel gauge should work fine normally wired, however if you fit a TD5 speedo, it has a damping mechanism for the fuel gauge and warning light inside it so that it doesn't go up and down going around corners and the fuel light only comes on when the needle reaches the orange sector of the dial instead of flashing on and off from 1/2 tank. Does the temperature gauge work ? Do the warning lights work ? Having fitted all of the above TD5 bits to an '86 90 I can assure you that the dash will probably be the least of your worries Mo Quote Link to comment Share on other sites More sharing options...
Darren Posted January 24, 2008 Author Share Posted January 24, 2008 Thanks Western - just what I wanted Thanks for the info, Mo. The temperature gauge does work (when the engine ever decides to warm up, but that's another story) and all of the significant warning lights seem to work - main beam, indicators, hazards, oil pressure, charge, diff lock and low fuel. The only one that I can think of that doesn't is the handbrake light. It's entirely possible, however, that it's just not connected but the info that Western has provided will help me to figure that out. The glow plug light doesn't work, but then the Iveco engine doesn't have any glow plugs Quote Link to comment Share on other sites More sharing options...
western Posted January 24, 2008 Share Posted January 24, 2008 Handbrake switch wasn't fitted to all 90/110, so it's probaly not on your vehicle, take the handbrake rubber gaiter off & you'll find a small plunger switch if it is fitted, you can wire it in, or if not fitted you can do it by reading how to fit a park brake warning light on a 90/110 Quote Link to comment Share on other sites More sharing options...
Mo Murphy Posted January 25, 2008 Share Posted January 25, 2008 I don't have a hand brake switch on mine either but I usually find the lever being in the up position and difficulty pulling away is a bit of a giveaway Mo Quote Link to comment Share on other sites More sharing options...
Darren Posted February 11, 2008 Author Share Posted February 11, 2008 Thanks chaps, all useful info. I haven't done too much to progress the wiring issues but I have just replaced a lot of the dashboard and removed some non-standard switches. Now that everything is physically back where it should be I can tackle the wiring next Quote Link to comment Share on other sites More sharing options...
Mo Murphy Posted February 11, 2008 Share Posted February 11, 2008 Good luck, 'tis the work of the devil Mo Quote Link to comment Share on other sites More sharing options...
