Hi, this is initially a request for help - quite likely from Rustscrat - and is part of the engine swap plan.

What I'm seeking, is the pre-multiplex wiring for a 1.4 petrol (KFX) with chipped key, including ECU and immobiliser details.

I'll be splicing in elements of the Xantia "faisceau de cablage" to use the Xantia Texton box, rather than the chancer's unlock method of unplugging it while running on a car.

We are within about ten days of the physical swap starting.

Cheers, Adam.

Fantastic! That is the only immobiliser diagram I've seen which relates well. My 605 wiring diagrams are quite different there.

The ECU pinouts are very different between KFX and RFV as well. Many thanks.

Great addo!! So pleased that Rustscrat has been able to sort it out for you!!
Hey if you send me a case of VB I'll errm make sure it gets to him!!

I'd probably have to make it two cases. It's a four hour drive each way between you blokes and unless you're on the wagon I don't think it's possible to drive that long looking at a slab without cracking...

Another bump mainly to thank Rustscrat; the swap is well underway and the immo diagram above is worth a mint. I'll repeat this detail elsewhere, but for the sake of convenience the M49 (pre multiplex) immobiliser box is more or less behind the headlight dipping roller switch, to the steering column right side.

Cheers Addo, keep us informed.:thumbsup:

Picked up an odd wire not in the diagrams.

8631, it's off the 16-way plug originally for the immobiliser box. I'm guessing it interfaces with the central locking box, by it's first two digits. Obviously not essential to operation, but inquisitiveness gets me every time.

Everything else inside the dash is spliced in. There's even an 820 wire in the immo harness, not shown on the schematic above - very handy.
