Hi,

I have a 2009 Citroën C5 X7 and I’m looking for the driver seat main harness plug wiring.
Does anyone know which wire color corresponds to which function (power, ground, CAN, seat belt switch, etc.)?

thanks in advance!

The wiring isn't identified by colour. Colours can, and do, change along the loom as joins to other wires are made.

The individual wires have numbers printed on them repeated every so often along the length. You will probably have to peel back some of the loom covering to expose this.

Can't help with what they actually are though, sorry.

ok, and could you maybe help me with what is needed for the electric seat and seat heating to work? Positive, negative, etc.?

Are you wanting to fit electric seats to your car but it does not already have electric seats ?
