That's a lot if complicated wiring for a 50 year old truck. Maybe best to ignore the battery meter and use a volt meter at the battery and leave the fan power leads at the battery block to confirm a charge state. Rats, I really wanted to retain a factory appearance.
Any one know of a volt guage that replaces the amp for a 72?

You're welcome.

Check with fellow member T-Bone ... I don't know if he's still doing it or not, but he used to convert 76-87 truck voltmeters to work in 67-72 clusters. I believe he was using the 67-72 face plate to maintain a fairly original appearance.
