Ahead of time sorry for the kinda long read........... I just picked up a 94 V6 stang to began my build with for a killer steal, I had a LS2 to put in it but someone came and offered me money I couldnt refuse for my setup so now I am putting a 4.6 2V in the car. Of course some of you older stangnet members remember I had a 98 GT that I was going to put a 04 PI Motor in that I aquired when I worked as a tech at a Ford Dealership, well as you may remember I traded the car for a Drag 89 Fox and have been sick ever since. Because of this I have a very nice 04 4.6 Block with 10,000 miles on it still sitting on a engine stand in my garage since.... My question is since the car I am putting the motor in was a sixer and I have a 04 GT wiring harness but not computer would it be easier to just use that or order a FAST Engine Management System MSD, or any other brand? My only other question is I only have the engine harness for the PI Motor, so how would a tuner be able to tune the car with no OBDII port to hook to the harness? It maybe a dumb question but before I start to tackle this problem I am trying to get my ducks in a row before I began. My plans for the motor are H/C/Kenne Bell so which do I do to help in the long run? Again Thanks!
