Aly90 Posted June 21, 2019 Share Posted June 21, 2019 Hi Folks Looking a bit of help with the fuel gauge wiring on my 1985 90. I've done a full rebuild on this over quite a long time and the wiring for the fuel gauge was in a bad state so I ordered a new loom, I was able to goggle and get the wiring at the sender unit sorted but where does the other end go as I have a Black wire (earth), green/brown wire which I can see but the white/blue wire I can not find a match for at the bulkhead. Would anyone be able to post photos of where these go. Thanks. Quote Link to comment Share on other sites More sharing options...
MR-HIPPO Posted June 21, 2019 Share Posted June 21, 2019 Hello and welcome to the forums. Is this a new chassis loom from Auto Sparks? The Auto sparks chassis looms seem to have the wires for both the petrol and diesel models. When fitting to a diesel engined vehicle, you may well be left with a spare White/Purple(ish) where the loom joins the main harness at the bulkhead. This is normal, and you can leave it unconnected. On a V8 engined vehicle, this White/Purple would provide power to the electric fuel pump. Quote Link to comment Share on other sites More sharing options...

neil110 Posted June 21, 2019 Share Posted June 21, 2019 (edited) white/slate goes to low fuel level warning light. Petrol fuel pump is plain white White/purple goes to the coil on a petrol engine https://www.landroverweb.com/Pdf-files/Manuals/Defender-90-110-workshop-manual-5.pdf https://www.autoelectricsupplies.co.uk/cms/files/colour_code_for_vehicle_wiring_-_new_order_2.pdf Edited June 21, 2019 by neil110 Quote Link to comment Share on other sites More sharing options...
Aly90 Posted June 22, 2019 Author Share Posted June 22, 2019 Thanks for the help, as you can see the tank end is sorted but where does the other end go. I have looked in the bulk head wiring and behind the dash and have not found any wires the same colour to connect to, the one easily sorted is the black to earth.
