Hi. Never wired up a towhitch before, can anyone tell me what each colour wire is supposed to be for so I can wire it into the car?

cheers

PS> if anyone knows what colour wires I need to connect it to in a pug 405 estate that would be very helpful

Do a google search for towbar wiring and you will get the info about which colour to use for which lead.

As for connecting it to the car, use a circuit tester to see which one is live and use the blue block connectors to "piggy back" the original wire.

cheers longwayoff. I'll have to dig out a haynes and look at the wiring diagram for the 405.
