ammeter with aftermarket harness?
I WOULD NOT install a "full current" ammeter in a modern car or only if the bulkhead connector has been dealt away with. You might have to do some wiring changes to the harness
Here is the "general idea" with ANY ammeter. You need to separate ALL loads except the starter, and provide a "common point." The battery ONLY (no loads) connects to one side of the ammeter, and the other side of the ammeter you connect the alternator output, and all the loads . If you "screw up" and the ammeter reads bass-ackwards, you just reverse the ammeter connections
This simplified diagram is as good as any. It is the "stock" factory wiring, but it illustrates the point
