Cadillac CTS Seat Wiring Diagram

Those are beautiful. The integral shoulder belt is about the only way to upgrade an A-body that didn't come with factory shoulder belts. Sebring vert seats are similar, as are more sedans today.

I have front seats from a Mustang Cobra convertible I will soon be installing in my Dart. Not leather, but only $50 off craigslist. They have the upper loop for a shoulder belt. Only the driver's seat is powered, and it has integral control buttons, so the only wiring is to connect +12V and ground. Similar seats on ebay are $$$ plus $$ shipping.
