Charging voltage too high.

Biggest problem is figuring out where to mount it. You want it "dry" as you can, and away from engine heat, some. Basically, electrically you do this:

Locate the "ignition run" (IGN1) traditionally dark blue coming out of the bulkhead connector. "At some point" it will disappear into the engine harness, you can unwrap it. You cut it at some point

Basic wiring for a "Bosch" relay:

The above is a basic diagram. 30 is main power for the loads goin into the relay. So feed that from the starter relay stud through a big fuse or breaker like 20A

87, showing headlights here, goes to the cut end of your ignition "run" wire on the engine harness side

85 you ground and you can run this through a small toggle for a little bit of "anti theft."

86 you hook to the cut end of the "run" wire which comes out of the bulkhead connector.

You can buy relay sockets with a mounting hole and wire pigtail
