Alex Posted January 10, 2012 Share Posted January 10, 2012 I'm getting close to having my car mot'd now just the final bits of reassembly. After some help from James with how and where to fit relays and fuses I'm now waiting for some correct wire and stuff to arrive. I fitted my front valances and side lights and this is where Im struggling. I cant find enough wires!Each side light has a black,red and green wire however I can only see one green from the loom!I do seem to have to brown/blacks with spade connectors though and i cant see what they are for?Theres two purple and blacks for the horn and a redcand a black.......this is all from memory!Anyone got any clues?

JensH Posted January 10, 2012 Share Posted January 10, 2012 Original spec loom?From memory: Red is side marker (parking lamp), both sides. Green/red and green/white should be right/left turn.There shouldn't be a brown there!Black is ground. Link to comment Share on other sites More sharing options...

Alex Posted January 10, 2012 Author Share Posted January 10, 2012 Ok you think I was confused this morning you should have seen me this afternoon.....The wires from the side lights are red,black and green.....red is side light green is the indiactor and the black will be the earth(it must have been added when the car previously got fitted with fibre glass valances(now gone).So thats them sorted,my problem was....I could only find one green from the main loom but as luck would have it when I got home there was two a green and white trace and a green and red trace :B I really shouldnt go and try and look at these things at 10pm ;DBut the black and brown wires(2 joined together with a spade)are still there.But I cant see them on a wiring diagram.

JensH Posted January 10, 2012 Share Posted January 10, 2012 A photo would help... Is the black and the brown connected via the spade connector?Someone did ad an extra ground? Link to comment Share on other sites More sharing options...

Alex Posted January 10, 2012 Author Share Posted January 10, 2012 I definately seem to have two earths coming from my main loom that i cant find on a wiring diagrm. Also i still cannot see a reason for the brown/black wires joined by a spade. Is it just to wires for the horn? Link to comment Share on other sites More sharing options...
Richard B Posted January 10, 2012 Share Posted January 10, 2012 I think brown/black is for the horns.The black(s) are the earths for the lights / indicators. Otherwise they have to earth through the hinge pins!Earths aren't shown on wiring diagrams, to avoid confusion ;D ;D ;D Link to comment Share on other sites More sharing options...
Alex Posted January 10, 2012 Author Share Posted January 10, 2012 Oh.... i thought someone said the earths shouldnt be on the sidelights...Is the purple not the horn then Richard?Its all very confuddling for me :-( Link to comment Share on other sites More sharing options...

Alex Posted January 11, 2012 Author Share Posted January 11, 2012 I thought maybe you were right Bodders but I've looked again....The purple one is taped together with a black one,the brwon and blacks are shorter and also together,but in a different part of the loom....?Maybe theyre redundant wires?

If you've identified and connected all these, then I suspect any left-over wires are not part of the original wiring.Could a previous owner have customised the loom, laying in extra wires to feed an electric fan, or perhaps some fog/spot lamps?If they have followed the original Lucas colour scheme, brown should have a permanent +12v direct (unfused) from the battery, and black should be an earth connection. Personally, I never trust the wiring of previous owners - far to easy for the smoke to escape :-/ Link to comment Share on other sites More sharing options...

Alex Posted January 12, 2012 Author Share Posted January 12, 2012 I'll attempt a picture when I get a moment....I'm currently trying to make door cards for it.Not much to go now.....if only I could sort the blasted electrics!! :) Link to comment Share on other sites More sharing options...

Alex Posted January 13, 2012 Author Share Posted January 13, 2012 Thanks Richard and Bodders I may just hold you to that :)I've just come in from the garage now and I had another look at those wires.....If the purple was discoloured and they looked brown that would mean I have 3 connections doing nothing.....horn as yet not connected.I've been waiting on some wires and relays and stuff so no progress on sparky bits.Oh on a slightly different point.....I had 3 relays in my garage I bought a long time ago but worked out with some help that 5 was what I actually needed.I ordered 2 more and they came today but.....I've ordered 4 pin relays but my old ones are 5's....whats the difference?Do they do different things?Thanks,Alex Link to comment Share on other sites More sharing options...
James Posted January 14, 2012 Share Posted January 14, 2012 You should be able to rig up the relays to work as 3 pin Link to comment Share on other sites More sharing options...

James Posted January 14, 2012 Share Posted January 14, 2012 Sorry! I meant 4The 5 pin ones usually just have two extra "output" pins so you can connect two cables to them – useful when you want to connect two things such as left and right lamps. Saves you having to crimp two wires to one terminal. Link to comment Share on other sites More sharing options...
