Well, with the correct color coupe loop, it looks factory. Though I think I'm going to re-dye black when I restore the leather.
The heated seat portion took a bit of engineering on my part. I'll have to post the schematics. The newer seat uses a different control relay, wiring, and thermister since it uses the hvac data to communicate through the bcm, and the old switches just use a relay module and a switch.
To do it correctly, I had to run power, ground, and two signal wires to the switch and seat, illumination to switch, and splice the 97-03 driver's heat wiring and replace the thermister that's built into the seat. It was a bit of a project. There's a few other ways, but they only work on high (not full switched).
