Reply to "Back Up Lights"

In the early days, we had to take these wiring diagrams with a grain of salt. So I use a tone tracer to first find where the wire goes.

I just helped sort out my friend's early '72 this month and one of the issues was the reverse light being hooked up to fuse#3. I dont have the serial number but the SN is in the 3XXX count.

My factory service manual is a first printing, dated September 1973. When I bought it with the TSB book, it came with a factory wiring diagram dated 6/15/1972.
When I check for a reference to the back-up light circuit in the manual, all I find is that it shows the circuit assigned to fuse #12.
When I check for a reference on the TSB, I find an undated wiring diagram on the last page of TSB#9 showing the back-up light circuit wired to Fuse#7.
At one time, Mike Drew had three different factory Pantera wiring diagrams.
