Hi

I am currently running new wires for my offside front indicators ( and possibly Main & Side Lights ).

The existing wiring has been jointed several times in the past (previous owners) with wrong colouring etc and the joints were just twisted together!!

It seemed that although there were several black wires ( earths ) going to a bolt on the wing panel, that they were all joined to one black wire and spurred off that joint to lights.

Questions:
1. Is it be better to run an individual black direct to each light and cut out all the spaghetti of linked earths (& wrong colouring )?

I am also thinking about running the main lights of relays as the general consensus seems that this is the better way of doing things.

2. Can anyone give some input with circuit drawings / photos of how this is best carried out?

3. As far as wires are concerned i don't seem to be able to find info in searches on what size wire to use for what circuit. Again any info appreciated.

Thanks in advance.

Do a search for vehicle wiring products there web site will let you know what size of wire is suitable for what.

The earths all join on the inner wing and yes this does sometimes cause problems, as for the seperate earths it is up to you. The bolt on the wing joby worked good for many years on your landy, as they get older it is worth stripping them down and cleaning them up

8.75 amp for side lights relay triggers/switch. 17.5 amps for head lights ,main feed for relay vehicle is earth so doesnt make much difference apart from putting the point in accessable area

why do you need such big wiring for headlights a 60w bulb doesn't use anywhere near this amperage ......... use watts law to calculate the amperage draw off of each lamp you are wiring

60w on a 12v system = 5a

55w on a 12v system = 4.58a so even going for a 50% safety margin your only going to need 7.5a wire the main feed to the relay will need to be larger but not overkill

thats the common wiring used and even they burn on headlight connectors

Thanks guys

I'll be in touch with Autosparks soon to get correct colouring to help with future work so will pick up suitable cable from them.
Appreciate the input and will certainly err on side of caution etc.
