Hey people, just got my 1997 explorer 4r70w and 4406 tcase swapped into my ranger but need help with wiring. I was thinking of swapping the dash into the ranger to try make the wiring go better, is this a good idea or can someone show me where to go to find info on wiring the engine/trans. I will be cutting in the wiper cowl to install the computer instead of lighting wires.

thanks:

 

I think trying to swap out the dash is probably making a whole bunch of effort for not a lot of gain.
