03 Explorer Sub Amp

Take a look to see how many wires in this plug. Here are the connections at the amp for the eight pin plug: pin 8 = SW audio negative pin 7 = SW audio positive pin 3 = SW audio shield pin 1 = SW amp turn on pin 2 = BLACK/ orange = ground pin 6 = yellow = 12v batt pins 3,4,5 = no connection Always test to see if this matches what you have, BTW, seeing that this is a stupid Ford and they like to confuse the hell out of everybody (remember the red wire being a ground on Mustang amps? who else but Ford would use a red wire for ground ) I take no responsibility for the consequences of the information shared. Prepare your future. It wasn't the lack of stones that killed the stone age.

Thanks.  I think the input has only 4 wires.  Any ideas?

Also, what is the "audio shield"? I'm not familiar with that.

Audio shield is just that . . .a radio interference shield to keep the signals noise free like the outer braid in an RCA cable.Prepare your future. It wasn't the lack of stones that killed the stone age.

i'm guessing the BLACK/ orange are the signal coming from the radio, the red is ground, and the WHITE/ blue is power. That just a ruff guess though so dont take my word.
