Hi all,

I am installing an American Autowire wiring kit in my mustang and I am not 100% sure how to wire the gauges. I know that the AAW kit does not support the ammeter, so I am not really concerned about that.

So I assume that there is supposed to be a 12v switched wire going to the "ign" side of the voltage regulator on the gauge cluster and a ground wire that grounds the chassis of the gauge cluster to the dash. Is that correct?

Then each gauge (oil, fuel, temp) should have one wire going to the sending unit for the gauge and one wire coming from the voltage regulator. And all the gauges are grounded through the gauge cluster chassis. Is that right?

Thanks,
Daniel

 

that sounds about right, the one from VR is usually green/black. depending on the year, there's wiring diagrams here:

the ammeter is completely independent from all this (does not go over voltage reguilartor), you could easily run your own wires
