while this may not be of much use to many here, i thought i would post it up anyow to save those who DO need it alot of headache. major props goes out to "way2old" at automotiveforums.com for this btw as he provided me with it.
for those who are curious, a while back i bought an OEM ford amplifier on ebay for my carpc project as 1) our van didnt have one and 2) i didnt feel like paying outrageous prices for an Aftermarket amp and 3) i didnt need any massive power AND 4) it should work perfect as its designed to work with the stock speakers already in there. anywho, seeing as our van didnt originally come with the premium audio system, the main iso connector for the amp is not anywhere to be found and its nowhere to be found online. just recently got in contact with "way2old" after in a thread he mentioned having a book with a whole mess of wiring diagrams. he provided me with the following diagram of said iso connector. the other connector on the amp is for the audio input and did not have a diagram, but it should be a simple case of trial and error. i will document it here later.
