Talk about the 406's electrical system, what wires do what, how to add extra functionality, etc.

Yes thanks mjb, it may help to remove the inside panel on the offside (drivers side) to see if you have the same connectors, this would help me a lot - no screws involved just loosely held in with plastic tabs.

I showed the photo in the original post to Peugeot and they said the connections are for a trailer, still not 100%% sure. I'm now the proud owner of a circuit tester and have found out the following:
  • . brown connector (3 wires same as rear light connector) has one wire which is powered all the time - even with ignition on and all doors shut

    . blue connector (about 8 wires) has 3 of the contacts in the connector powered all the time - even with ignition on and all doors shut, none of the contacts are powered when the hazards are on.

    . yellow connector (4 wires - this is the one I thought would be the basic connector for the trailer - l.ind, r.ind, brakes, lights) doesn't give a squeak when the hazards are on or the lights - damn
Getting close to the point of hacking into the existing wiring and ignoring these extra connectors.

If anyone has any bright ideas or could please check their connections - it's just a five minute job - thanks very much.

I can't really help with the Pug (mine doesn't have towbar) but when I fitted a towbar to my Ashtray there was a plug for it on the loom but the advice was to just lop it off and use the wires as the real thing from GM was ridiculously expensivo.

I reckon it might be easier to use what you have and hack into the loom for the rest.
