im putting a 2003 mach 1 crate motor into my 97. it fits awsome everything works good or a few nickel and dime things. i need a wiring harness from the computer to the fire wall and a computer for a mach 1. if anyone has them or one of them or know where i can buy one let me

97, There are several versions of the ECU for the mach 1, i can't get you the correct one without a VIN from the car that the engine came in. These ECU's are also unflashed and will have to be flashed by a Ford Dealer. Is this engine a Ford Racing crate engine or did you take it directly out of a 03 Mach 1? I'm not sure if i'll be able to help you out with this project.

i ordered it from jegs its a crate motor a vin # is no good also would u be able to get a wiring harness from the computer to the fire wall

I can't really do the wiring harness either without a VIN, there are to many variables. I would contact JEGS and see if you can get some information from them. Was this a ford racing engine you purchased from them? If so you might call Ford Racing and see if you can get some numbers from them on what parts you need to make this work for you.
