ianmayco68 Posted April 2, 2021 Share Posted April 2, 2021 Hi all , I’m fitting a discovery 2 wiper motor into my project 300tdi 90 as I’ve modded the wiper system, 3 out of the 5 wires from the main loom match but 2 don’t , I think I no what wires correspond to each other but thought I’d ask here first as I don’t want a 🔥 fire after I’ve just spent years rebuilding it. So on the defender loom I’ve got ; black , green , red/light green , blue/light green and brown/light green. and on the disco td5 motor the plug that comes from the main loom I’ve got ; Black, red/light green, blue/light green, white/green and green/slate . On the two that don’t match I’m presuming that the green wire matches too the white/green and the brown/light green to the green/slate . I looked on the wiring colour information in the tech archive but it wasn’t much help . cheers Ian Quote Link to comment Share on other sites More sharing options...

monkie Posted April 6, 2021 Share Posted April 6, 2021 Is this any help? I struggled to find a comprehensive list of land rover specific wiring colour code so I made my own from my 1988 loom and circuit diagrams: G=green, LG = light green, R=red, U=blue, W=white, O=orange, P=purple, N =brown, B=black, Y=yellow, S=slate(grey), K=pink. G fused ignition on GR left turn signal GW right turn signal GP brake lights GN reverse light GB fuel sender GY heater blower motor switch GS heater blower motor switch LGG oil temperature LGW oil pressure sender LGB screen wash pump LGP trailer warning light LGN hazard switch to flash relay R running lights RO right side/tail RB left side/tail RY rear fog RLG wiper motor RW 12v socket illumination U head lights UO right main US left main UK left dip UB right dip UG wiper motor W unfused live ignition on WR ignition switch to starter relay WO ignition switch to heater blower fuse and radio WB rear window heater WS fuel sender to guage WN oil pressure warning lamp WY hand brake warning light WG Heated rear window switch to relay/dash light P unfused permanent live PG fuse to heater blower motor PO seat belt warning light (where fitted) PW interior cab light PU door switch (where fitted) N permanent live from positive terminal bus on starter solenoid NLG wiper motor NY charge warning light NLG flasher relay NW fuse to heated rear window relay B earth BU diff lock engaged warning light BW brake warning light BR hazard switch illumination BK heated rear window relay to diode BS heated rear window diode to voltage sensitive switch YB Glowplug Feed 2 Quote Link to comment Share on other sites More sharing options...
ianmayco68 Posted April 6, 2021 Author Share Posted April 6, 2021 Cheers both , sadly not as the green/slate wire is for the heater on the defender and the wiper motor on the disco td5 . I’m pretty sure that green ignition switched live on older models changed to white/green on later ones so I’ve wired those together and the green/slate to the brown/light green as the others match once I’ve wired in to a fuse I’ll run some wires to the battery and check I’m correct before bolting it all up .

monkie Posted April 6, 2021 Share Posted April 6, 2021 I'm afraid my wiring is a bit too 20th century for the Td5 era! 1 Quote Link to comment Share on other sites More sharing options...
