C7 Seat Adapter Harness DIY?
I've found the pinout and the seat-side connector part numbers to get the seat adjustment motors working. I don't have the part numbers for the mating connectors for the body-side connector for my 2008. My car is a 3LT so it has the memory seats, power telescoping steering wheel, and heated seats. I'm not sure if it has side airbags. The 1LT seats I bought do not have lumbar, heating, cooling, etc. to worry about.
What I have so far is:
TE Connectivity 2301462-1 connector
Pin 1 goes to ground and I need 1x 19331733 (1241408-1)
Pin 2 goes to power and I need Pin 2 1x 19300440
Pin 9 goes to power but does not need a conductor?
What I need is:
Diameter and length of seatbelt anchor and tensioner bolts (I ordered the bolts from GM and they are more than 10 days delayed)
Pinout for C6 harness
Part numbers for connector and conductors
Info on how to make telescoping steering wheel work
Info on how to make seatbelt buckle switch work
I've seen mention of a seat position sensor but don't know if it's applicable
Anything else I'm not thinking about for the driver side?
Info for passenger side occupancy sensor
Info for passenger side seat belt buckle
Info for power adjustment of passenger side
If your car is the 3lt then it should have side airbags. Check the leather on the side of your seat, you should see "Airbag" or similar printed into the leather. Assuming yes, you need airbag simulators, which is just a resistor bridging the OEM yellow connector. I don't know the resistance but you can Google it to find out what GM used in the era.
Since you have a 3lt, your passenger seat already has power, so you luckily don't need to build a harness to get power over to that side. You just need a similar harness as the driver's side.
For the occupancy sensor, it's easy to pull out of the stock seat but you can buy one for ~$70 on eBay. Need to look for a 3 pin sensor from an 07ish GM vehicle. Mine came from a truck. I had a hell of a time trying to install it into the seat and gave up. So my sensor is rolled up, secured in that position, and sitting behind the seat. Car thinks there's always a passenger there so I leave the passenger seat buckled at all times. Kind of annoying but worth it to have a working airbag when I do have passengers.
I'll add more info as I think of it and find it.

Judging by your progress, you've already read these, but anything to help:

From my notes after my initial call with Dan from Vetteworks, he said you have to use the wiring harness out of your C6 passenger seat, which I did and is in my writeup. Driver's seat is just the 3 main wires that you've already figured out for power.
