Is the wiring harness inside the truck { fuse block, ignition , radio etc.} the same with a/c as without a/c? Thanks

On the 71-72's the AC portion is separate from the rest of the fuse block harness. The tie in to the harness is at the blower switch plug as the terminal fits into the plug held in place by the little tab. Power for the harness is made possible by a direct power wire plugged into the fuse block.

I am not familiar enough with the 67-70 AC harnesses to know if they are the same as the 71-72's but I suspect it is the same setup.

There may be some other minor differences, but it looks like the AC harness could be made to work with the non-AC fuse block.
