Hello - I am dealing with a cut up factory harness minus plug and need help identifying the 4 wires:

1) Green with white stripe
2) red with black stripe
3) Blue with yellow stripe
4) Black with yellow stripe

I am trying to hook up AEM gauges and need to know which one is accessory power.

I bought a metra harness and trying to match them up just so I can figure this out...

On the metra harness, I have the following:

1) Red - 12V Ingition/Acc
2) Yellow - 12V constant
3) Orange - Illumination (Which AEM will not use)
4) Orange with black stripe - not listed - Is this the ground?

Thanks a lot, any quick help appreciated.
