The Headlamp warning option is RPO T63.
The "extra wire" in the RPO T63 equipped trucks is from the instrument panel lamps. I believe the ground is from the key inserted switch in the column.

I know this is a super old thread but I know you know wiring better than anyone else on here. Do you know what year c10s that this is a direct plug and play? I am guessing the 1981 and newer squares but it would be nice if it worked on some of the other ones. As usual, thanks for your knowledge in advance.
