MAD electrical upgrade question??

Well, sort of.

The black wire is connected to a welded splice in the harness and has a couple different legs coming off of it. Just make sure you find the one between the ammeter and the splice!

Pulling the instrument panel is not that bad if you lower the column. You don't have to pull it all the way out either, just enough to reach in to be able to detach the wires from the back of the ammeter.
