Doing a 351 motor swap in 66 bronco donor vehicle is 93 ford f150 motor and harness making the change on harness to be mass air have not bought ecu or transmission yet Question 1 the speed density motor and harness that I have can I use the 94-95 mustang ecu. plus is the 94-95 ecu pin locations the same as 88-93
Question 2 If I can use 94-95 ecu does it require anything else on the motor other than the mass air that is needed for the 88-93
Question 3 If I can use 94-95 ecu my harness has a plug for the transmission that is for a e4od is it possible to change plug connections to use 4r70w transmission

 

No and no.
Yes you need additional wiring for the MAF and sequential injection.
I'm sure you could but if you want to use a mustang PCM you will need a non computer controlled trans.

 

With regard to the tranny you might wanna use a non comp controlled to simplify things a bit, or get everything from 1 donor vehicle
