Hahaha wiring its fun but can be a challenge an can make you pull your hair out haha. All I say study those wiring diagrams. I work on vintage stereo equipment anyways with restoring those old things so doing this I kinda am use to it but still your working on a bigger scale an you don't wanna mess up something then go boom lol.

The fact that they added a volt meter is probably a good indication that the factory ammeter quit working. It could be as simple as that black wire no longer being connected to the starter solenoid BAT stud. But while you're working on the wiring, it would be a good idea to take a close look at the rest of the ammeter wiring (including the wires under the dash) just to make sure it's all in good condition and still connected as shown on the diagrams Lugnutz65 posted.

Thanks for all the help ray! I am going to go ahead an check the rest of the ammeter wiring to be safe before hooking the gauge backup an sending power through all the wiring. You have a point maybe that's why they added it but idk the truck was setup to pullna trailer cross country apparently cause whoever owned it in the past traveled a lot which I'll post why they mighta added that meter in a bit.

All I did was snag a fuse block clip for my radio spot and that's all I did to it. I'll let ya have it for nothing. No need for it on my part.

Thanks man!!! Its cool about the wiring diagrams I can use them when you get back. But that harness will for sure come in handy I can tell ya that!!! I owe you big time man thanks!!!

Exactly that's what my truck is is the oil gauge was plumbed in an how could it have a oil warning light which then with the help of the guys who posted above helped me find out the black wire was for the ammeter.

Sure made wiring the gauge cluster a lot easier to adapt to the newer wiring harness......Kieth

Thanks for the info kieth!!! I'll deff check out the 73-87 trucks if I need anything extra.
