BCM Connector Wiring Chart for VXII-LS1 Needed

Hi Guys,

I'm in the last stages of a Small Block Chev 400 conversion to OBD2 using the 0411PCM and to save time used the VXII-LS1 wiring harness. Everything has been connected up in the engine bay etc, and I now just need to tie up the loos ends and wire the rest into the car.

Its a 1985 Pontiac TransAM so I have to do everything from scratch, but my biggest problem is trying to sort all the wires from the "C" connectors that go to the BCM.
I also have the long plug that I think is for a cruise control module or Drive-by-wire throttle body, and a small plug as well.
Somehow these plugs need to be accounted for, but I've got no idea. I also don't have the BCM for it, as I'm using a later model transAM dash cluster for the gauges, so I don't need anything converted from/to CANBUS/analog.

Does anyone know where I can get a wiring diagram for the BCM, I'm assuming from the pictures of the bcm I've found that it doesn't plug into anything else, is that correct?
So i should just be wiring the loose wires from the connectors back onto wires from the other connectors and bypassing the conversion, yes?

Lastly do i need to do anything with the long plug and shorter plug for these, or can they be left alone?

Any help would be greatly appreciated.

Cheers.
