Hi guys,

Got a quick question for you, my uncle has picked up a genuine Peugeot tow bar for his 2004 307 sw. It didn't come with the electrics so I was going to pick up a standard wiring kit. I know Peugeot's are fussy with there wiring, can I just hook the electrics up straight to the power feeding the bulbs or do I need a special adaptor to attach to the van or can network?

hi....you will need a smart towing relay ,,like this;

That's what I thought, it always pays to check. Cheers Noddy

Not often I don't agree with Noddy, but when I fitted a towbar to my wife's 2005 307sw I just connected the wiring near the rear light cluster.
It's till working fine eight years on.
I did wire in an audio bleeper btw, nothing difficult about this job.
Wiring in the caravan accessory plug (the grey one) was a bit more involved, not because anything was difficult, but lots of trim had to be taken up and replaced.

Warning: the following is reasonably informed speculation. If you burn out the BSI or wiring harness of your car, don't blame me...

Not sure, but if all the functions in the clusters have their own wires (none of that PWM'ing described in the link), then the situation should be the same as for any old pre advanced electronics car, simply another set of bulbs in parallel with the original ones (no need for the relay to sort out the PWM'ed signal into distinct wires for brake vs rear light on the trailer).

Only obvious potential issue I see would be if the BSI isn't capable of delivering the increased current on the lines in question. In that case, some sort of relay would be required, the linked (or similar, specific for the car in question) or a set of standard ones.

My wife's is a pre facelift model, I dare say that was the difference.:thumb:
