Wiring Loom Help! Rb25det Into '71 Volvo Conversion

[hecticunt]

Hi,

I'm hoping this thread is in the right section because I couldn't find any section with electrical questions.

Anyway, I've viewed a whole bunch of wiring diagrams but haven't been able to find what I'm looking for.

I'm trying to get the dash and other thing's in the cabin wired up in the car I have fitted the engine into ( yes its a volvo )

There is a big white plug on the engine harness, close to the Big blue plug that goes into the ECU.

The white plug connects to the harness inside the cabin for the accessories, in particular, the instrument cluster inputs (speedo, tacho, temperature, boost gauges etc.) I think it also has the wiring for the Ignition switch on it and a few other relays.

Either way The plug broke when I was being removed, which is ok because I only need to use the necessary outputs to get the car going.

The diagrams that I have seen with this plug on them (a lot of the engine wiring diagrams don't even have the big white plug on them) only have codes to identify each of the outputs for the wires.

Can any one point me in the right direction here, it would be much appreciated.

I've just circled the plug I'm talking about on this diagram (sorry bout the size if I reduce it anymore you cant make out any of the letters, its already a bit distorted.)

I'm thinking of stripping the harness in the cabin and tracing each of the wires from the plug to the relevant component, like the ignition switch for example. But when it comes to the instrument cluster its impossible to figure out what goes where. I might try looking for a wiring diagram just for the instrument cluster.
