slayor2005 Posted September 7, 2021 Share Posted September 7, 2021 Hi first time posting on site even that i have owned my Landy 90 for over 5 years . My problem is have brought 3 looms from a well known on line site because i put a new back door on with heated window and i put a wiper on plus wash , now i have all the looms coming in the back of the bulkhead i have found homes for some of them but still lost on a few . what do the two very small cable maybe 2amp do, one is black which is ground that i know and the other is white with black trace both have female connectors and the third is all white with piggy back connector. All so looking to powering up second washer bottle motor via switch . have a few problems as it come out of factory with petrol engine and someone replaced with a 200TDi . Having lots of fun must of the time. Thanks Quote Link to comment Share on other sites More sharing options...
Maverik Posted September 7, 2021 Share Posted September 7, 2021 Hello, welcome to the forum! The wiring of that era is mostly standard Lucas wiring colors - there's' some good guides if you do a couple of google searches. Post up some pictures is always a help to identify stuff like this.

western Posted September 7, 2021 Share Posted September 7, 2021 Some go to a voltage sensitive switch, it's a yellow cased relay shape, sit in right front corner behind instrument pack, it prevents battery drain when engine is not running & alternator not charging if the heated rear screen is switched on.

slayor2005 Posted September 7, 2021 Author Share Posted September 7, 2021 Hi thanks Maverik have done a lot of research on the wiring colors the sad thing is the makers of the looms don't give any ideas of where they go just say that they ( the looms ) replace what was there but there never has been a loom there before. try and upload some pics very soon. Thanks again Quote Link to comment Share on other sites More sharing options...
slayor2005 Posted September 7, 2021 Author Share Posted September 7, 2021 Ok Western thank you, i don't have a yellow cased relay anywhere to be seen but i will try your idea and see what i can find, i suppose you know which color should go to it ?? Thanking you Quote Link to comment Share on other sites More sharing options...

monkie Posted September 8, 2021 Share Posted September 8, 2021 Have you seen my thread on this forum here about making my own looms? I went through similar problems and troubleshooting finding what colour wire goes where. I drew up a list of wiring colours used on the land rover wiring looms. I have copied and pasted a post from this thread below with all the correct colour codes I worked out: *Correction to my earlier post. Purple is fused permanent live (not unfused as I had put earlier). I also had missed off brown with red trace for the glowplug feed from ignition switch: 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 fused 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 NR ignition switch to glowplug relay 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 from relay Quote Link to comment Share on other sites More sharing options...
slayor2005 Posted September 8, 2021 Author Share Posted September 8, 2021 Thanks Monkie looking very interesting will run though that and see what I make of it. Now I have taken a photo of the 3 wires that are confusing me if anyone knows where they go. Quote Link to comment Share on other sites More sharing options...
slayor2005 Posted September 8, 2021 Author Share Posted September 8, 2021 The one on the left is white with piggy back connector the middle one is white with black trace and far right is black which is a ground i suppose , sorry for poor photo quality. but as i said the connections are half the size of standard maybe 2amp Thanks Quote Link to comment Share on other sites More sharing options...
monkie Posted September 8, 2021 Share Posted September 8, 2021 Which end of the loom is this? White is unfused live feed when ignition switch is on. White with black trace is heated rear window. Black is earth. Are you sure that is black, it looks to have a grey/slate/white coloured trace from your picture? Quote Link to comment Share on other sites More sharing options...
slayor2005 Posted September 8, 2021 Author Share Posted September 8, 2021 Hi Monkie, It is without doubt black its looks grey in the picture i just had a lot of trouble trying to take it and then getting it uploaded just not my thing. The end showing is the dash end the third loom, starting at the rear door with wash wipe and heater ( no 1 ) then coming through chassis ( no2 ) and this one coming into dash via bulkhead and that's the rubbish picture.
