I knew the comp would be diff, the main question is this, the wiring, from the computer forward is the only thing that needs changed right?? No need in changing the dash wiring?
I just did this swap listen to me...I took a 92 GT Vert 5 speed, and put it all in a 91 Notch 4cyl auto
1. Change the motor, trans, computer and engine wire harness.
2. Change the headlight harness also. Reason being, the alternator plugs are on the passenger side on the engine on a 5.0L. The alternator plugs are on the driver side on the engine on a 2.3L.
3. You do not have to change the dash wiring. It is all the same, 4cyl, 8cyl, hardtop/conv/notch. All that goes to is the air bag plugs, headlight harness, and selenoid. All plugs are the same
4. Change the fuel lines. The fuel lines run on the driver side on a 4cyl. The fuel lines run on the passenger side on the 8cyl.
5. If one trans is a stick and one is an auto...you will need to change the transmission harness. No big deal...it runs along the drivers floor under the carpet, and plugs into a harness in the left kick panel area.
6. You will also need to change the clutch pedal box. The plugs that plug into the box, are all there on an auto car. Ford just put dummy plugs that loop a wire around.
7. Another thing too, the accelarator cable is run through a different hole in the firewall, but its not big deal. No drilling necessary, Ford just puts a rubber grommet in the other hole. Oh..accel cables and cruise cables are all different length too.
8. Just take EVERYTHING from the 5.0L and put it in the 4cyl car. I used all the the 4cyl
suspension, I didn't change brakes, springs, spindles, struts, lowers, steering rack....nothing like that. I will though soon, just because the car handles like a 4ycl Mustang.
I would do this swap again any day. I did it in 3 days. 6-8 hours per day BY MYSELF. I had a hoist and a forklift. My only advice is to get a friend to help you. There were some frustrations I delt with because I had to man three things at once.
