drewbar Posted February 3, 2014 Share Posted February 3, 2014 Hey guys, I have just picked myself up a defender, its got a bit of a history, being a 1990 90, started life as a pick up and has been converted to a station wagen, and some where along the lines, the chassis has been replaced for a glavinised item and the 200 tdi swapped out for a 300tdi Enter me purchasing the vehicle as a "project" None of the rear lights work a part from the OSR tail light, , I've been through and replaced all the bulbs and fuses etc, the main problem comes in the rear lighting harness where it connects in the engine bay, I have a whole load of wires here not connected to anything. I have found some wiring diagrams online to help me out, but I dont know how to tell if the harness is the 200tdi item or a 300 tdi item or if there is a difference at all for that matter. The other thing that would be very helpful which I cant find is a pin out diagram of the of the connections for the rear lighting harness in the engine bay at present I have a 4 track block connector and a 6 track block connector. If anyone can help me out or point me in the direction of some useful thread that would be great! Quote Link to comment Share on other sites More sharing options...
western Posted February 3, 2014 Share Posted February 3, 2014 but I dont know how to tell if the harness is the 200tdi item or a 300 tdi item or if there is a difference at all for that matter. there is a difference the 200tdi & older looms have multi-plugs cased in rubber, from 300tdi on the are plastic outer casing. if all the multiplugs are rubber just match up the wires colour codes, some 1,2 3 & 4 pin plugs go to a large plug with more connections & will only fit in one place.

drewbar Posted February 3, 2014 Author Share Posted February 3, 2014 OK great, it has the plastic type plugs so it is the 300tdi loom then, that should be a big help as I at least know which wiring diagrams to use Quote Link to comment Share on other sites More sharing options...
drewbar Posted February 5, 2014 Author Share Posted February 5, 2014 OK, so I found the source of my problems in the form of this!! A disgusting amount of crimps and corrosion but not to worry we can fix this! However I also found this plug that I can't identify from the connector library or my wiring diagrams, it was cable tied to the towbar under the vehicle and runs off of the rear lighting loom as well Quote Link to comment Share on other sites More sharing options...
western Posted February 5, 2014 Share Posted February 5, 2014 round plug is the fuel tank connection for a 110. on 110 there is a sub harness from the plug to the fuel tank sender unit to run the gauge. assuming your vehicle is a 90, then that plug needs to be weather proofed & secured out of harms way.
