Had a little bit of spare time today, so I whipped out the front seats, centre console and glovebox, then added the new cables to the trunking going across the car. I installed the four Onstar wires into the main dash loom plug and they are also copied into another plug which sits behind the dash, so those final connections will need to be completed when the dashboard is removed to swap the dash loom.
The Onstar aerial cable simply connects to the dash wiring loom underneath the centre console, so that was installed there.
The red circles indicate the connected Onstar cables and the remaining copied cables which will be connected once the dash is removed. You can see the wiring plug in the last photo in the above post, I believe it connects to the rear view mirror loom.
So all the additional cables have been run inside the original trunking and also taped to the original loom where possible. I am trying to do as neat an install as I can.
