Im looking to splice my donor cable driven HVAC wiring onto the end of a hacked set of wires coming from the digital climate control. Car is an 88 GTA Notchback...

It's the second last bit of wiring that I need to finish before I drop the engine into the car and get it fired up. Door wiring is the next part...

I've looked through the service manual and all it has for schematics and wiring is the cable HVAC system, not the digital one. If push comes to shove, i'll transfer the whole cable HVAC system over but would like to keep the push button controls just for kicks.

Does anyone have any wiring diagrams for this so I can compare and match up the proper wires that pass through the firewall to control the fans and A/C? Colours of wires are signifigantly different between the 2 sets (digital and cable/vacuum driven).
