Be aware that your C3 BSI won't be configured for the C2 Engine and components. I assume you know about matched engine ECU, BSI and transponder chips in the Keys?

Body Control Unit (but I would guess that BSI stands for it in French).

Plan is to use the c2 engine loom and ecu and alter plugs so connects to the c3 chassis loom. Then tape c2 key to the barrel of c3

That wont work unless you also have the BSI from the donor car. The ECU, BSI & transponder chip are all a matched set, if one of them is different the car wont start.
Apart from that it shouldn't be too difficult a task as the C2 & C3 are practically identical electrically. I would imagine the BSI would be a straight swap.

That's the usual British use but I'm sure I've read here that in French it stands for Boite Systeme Integrale (there's a bunch of accents as well - sorry) which literally stands for Integrated System Box. All much of a muchness really.

I think it is actually 'Boitier de Servitude Intelligent' Paul.

Not heard of that one Marc. I was just passing something I'd seen.

I could be mistaken Paul, but it seems in common use on some French sites. :wink:

Have you seen whether the Haynes manuals for the C2 / C3 have what you need? They do have some wiring diagrams in them. Quite cheap on the bay at about £11-12

All the wires are coded. The colours are irrelevant and mean nothing, and the pin layouts have been known to differ vehicle to vehicle, but the codes printed on the wires tell you what they are. If you compare the wiring identifier codes from the same ECU plugs on the donor cars that should be enough to match them to the correct positions on the new car

I've listed a lot of the wiring and component codes on our Wiki here:
