Vic, it's very confusing because options aren't included in section 12 (wiring diagrams) of the AIM. But going by the Fisher Body manual and the A31 and C06 option pages in the AIM (and my car which has both options), here's the breakdown as far as I can figure it out. (look at the pictures for reference)
A (hot) Red wire (#10 below) comes from the Horn Relay and goes to the Circuit Breaker mounted to the firewall. Another (hot) Red wire (#10 below) comes from the other side of the Circuit Breaker and goes through the firewall into the cabin. That red wire then splits and goes to the Power Top switch and the orange/black wire connector (#14 below) in the wiring harness taped up under the dash for the Power Window Ignition Relay. In addition, a Pink wire from the harness (#11 below) also comes from the Accessories port on the fuse box to the Power Window Ignition Relay.
