ok. i just got the amplifier ive been looking for in the mail today. its an OEM amp from a '95 windstar. got it off ebay for $25 shipped (better than $200+ from the dealership
). anywho, through some extensive google searching, ive been unable to find a wiring diagaram of the one plug on the amp. so far ive been following
this page extensively for help on the amp situation, but none of the plugs look right. here is my 1337 mspaint rendition of the plug
there is only one other plug on the amp, but that is the square plug for the audio input (as noted on the page linked to earlier).
