VS V8 HI BCM Wiring Diagram / Pinout

[Firstbuild_HZ]

Can anyone out there help me?

I'm after a pin out for a 149 HI BCM out of a 1996 VS Caprice.

If at all possible does anyone also have the wiring information for how the BCM "talks" to the PCM in regards to starting the car? ie what wires does the PCM get the "start the car"security signal from the BCM?

Any help would be appreciated.

Its on the ALDL data bus which goes out to most the devices in the car, including the bcm. The aldl line is also often called serial, data, or serial data. Its more often than not red with black stripe.
