EGR/non-EGR differences on the 2.9

[danger88ranger]

The wiring harness on my truck is pretty messed up, currently my tps sensor wiring is faulty(i pulled codes), my fuel pumps are direct wired, and a few other misc. things that have really bugged me. I went to the local yard today and found a 90 ranger with a 2.9. I know these are non-egr motors, but how similar are the main wiring harness'? If they are different what does it take to do an egr delete?

Obviously, it isn't wired for EGR. There is an electrical vacuum switch and a pressure sensor.

1986-87 Bronco IIs are a dime a dozen. That would make a much better donor for this.
