Yes, on the MADD deal, but I kept my amp gauge, but it isn't tied to the rest of the car. The wire that runs from the batter to the alt goes into the amp gauge. The original wires that was going to the amp gauge I tied together.
Works perfectly. Though he doesn't recommend it at all. So I wouldn't ask him about keeping it. I've also got a trio of gauges under the dash with live oil and temp gauges and the volt meter.
Can you not see in the post either, if so I'm sorry. I'll try again. Could you pm you email again.
