Tow-bar elec socket wiring

started wiring up my tow-bar socket today but got stuck and downed tools until I can get good advice as I don't know what I'm doing :blush:



got the first bit OK

function	socket	Car harness
Left indicator	yellow	Green/Red stripe
Right indicator	green	Green/Yellow stripe
Brake lights	red	Green / White stripe + dots

but here's where I stumbled, the socket has seperate wires brown (right light) and black (left light) and I'm guessing that both these socket wires connect to the single car harness wire as below:

Side lights

function	socket	Car harness
Right Light	brown	Red / Yellow stripe
Left Light	black	Red / Yellow stripe

and I also assume the earth connects as below:

function	socket	Car harness
earth	white	black

if someone can double check and confirm the above is OK (or wrong) I'd be very grateful
thanks

if there is only one red/yellow wire feeding both rear lights then yes connect them together but if there are 2 find out which one goes where and connect them to the brown or black as appropriate.
The Earth is correct Black to white socket.
The idea of separate wires is you will still have one working tail light if one blows.

many thanks Gilbert

will take it all to bits again tomorrow :S

You don't have to use the car earth wire(black)
You can take the white wire from the socket and earth it anywhere on the car using an existing bolt or hole.
Just make sure you get a good earth and use a star washer to bite through the paint.
If you have reassembled it all and put the seats etc. back you could cheat and run a couple of wires from the rear light units and splice in to the tow bar wires at a suitable point?
I did something similar on my first Jimny.

When I wired mine up using the guide from this site, I found a couple of the wires were wrong/different. I didn't write down which though

Anyway, you may find you have to play around a bit to get the right ones.

Where physically are you tapping into the car wiring to do this please?
