20G orange. From clock, Lighter, courtesy fuse to connecter S140 which splits off 5 ways. 1 to the clock, 1 to the cigar lighter, and 3 to each of the courtesy lights.

Thanks for the information I appreciate it. I got the clock to work all it was it just needed to be oiled but it won’t work want to put it back in the bezel. I think it’s a ground problem so my question is what part of the clock grounds on to what ? do you know?

The gauge cluster metal frame is grounded. It is a slip on blade connector on my 71.
