4.0 swap in progress

[blk93notch]

so im putting a 4.0 from a 93 ranger into my 90 that had a 2.9. did research on wiring and found that a 91 explorer harness would be a plug and play. i got the engine bay harness and cpu. now i have the 2.9 out and the 2.9 harness out. im ready to put the explorer harness in and noticed that the connectors comming off the 93 engine cant be found on 91 harness. im guessing i need the 91 engine harness also. im not worried about the egr fromt the 93 casue im blocking it off anyways and the 91 explorer didnt have it. so if anyone has did this swap can you give me a pointer or is it right in front of my face that i nned a engine harness from a 91 explorer or ranger.

I would think you need the 91 harness.
