volvo 900 immobiliser

Hello there!

I've got a serious issue here with my 1996 B200FT of a volvo 945 (European version). More precisely, wiring problems with the immobiliser (no alarm, just immo with keychip). I've managed to accidentally disconnect two wires of the immobiliser unit and don't know where to connect them for my engine to start: BLUE and YELLOW-GREEN; there are a total of 8 WIRES coming out of the immo unit(2 from the coil ring, 2 in an unused plug, and 2 going to the fuel ECU).

I've checked the wiring for the engine, from the spark and fuel ecus and their sensors, and it's ok.

So.. if anyone can help me with either the pinout/wiring info on the immobiliser OR the way to cut it out of the system, please drop a line here (or on pm if that's the case). I'd be greatly thankful to be able to start my car again.

I thank anyone in advance.

As i don't have the wiring diagram for this type of early 8pin immobiliser nor i have encountered on yet, i have one quick question for those who did and know:

What does this immobiliser actually do/ inhibit? spark, fuel or just the starter?

madviktor, welcome to Matthew's Volvo Site.

It should inhibit the starter and I still haven't found a wiring diagram.

well, found the area where the starter inhibitor relay should have been, but it wasn't, there was only a case of it, with a short in it, so not present.

did i forget to mention that the starter cranks like hell, but no start?

now where in the name of god can we find that info? (the 8pin immo pinout) `coz i'm kinda goin` ballistic..
