Got a matching tach I’ve been meaning to replace the old sunpro with. The wiring into the sunpro are black, red, white, and green. Where do these match up on the new gauge? I see bat and ground and s/g.

bat = red
ground = black
sig = green
white wire goes to the terminal next to the bulb.

Is it must me? Or are the BAT and GRD studs connected together via that bracket?
Is it a steel bracket, or hard plastic? If plastic, then no problem. But if conductive...%)

I realize that's the tach (or the same type at least) that we sell, but it just does not look right and I don't have a copy of the instructions handy.

It’s hard plastic. I bought it used from someone on here awhile back, they had changed it to a white face which matches my cluster. Just got to order the cup and it’s going in!

lets see the white face ;) and you dont need the cup, flush mounting those to the dash looks like a factory install

That would look sweet! But I’d need a whole new custom dash... no where to flush mount it at the moment.
