ok i understand the basics. of the SD to MAF.... my question is on the IST website that sells just the harness, it has an obd-i and obdII option,im assuming i need the obd-1, but i want to use the 94-95gt's maf. would i still be ok? like would i need a obd-1 to obdII connector. or are sn95 5.0's obd-1?? if so then i would be ok... 2ndly i guess my part list should consist is the IST websites obd-1 harness, a A9p computer(for my auto), and a 94-95 gt's maf.... and foxes intake box setup or i could go custom CAI which wouold be easier and get more ponies..... 3rd) would i need to do anything with the wires going to my fuel pump relay,tailights etc. if im just doing the harness swap... i really need to do more reasearch on the how to. but arent all you doing is adding this harness into your computer. like in theory if just taking the a9p moving somethings over to make room for the MAF.??
