TooMany,

You say you want to use a non-EGR engine for the time being? Are you still going to use the computer controlled distributor and carburetor? Still using the computer? I think the problem the other guy had was that maybe he was removing the computer controls from the vehicle. If you do not use the computer and the computer controlled carb and distributor, you will DEFINITELY have to rewire the 700r4. If you still use all the computer controlled components and just want to disconnect the EGR for now, I think you'll probably be fine as long as you leave all the wiring in place. Unfortunately, for one reason or another, I haven't had a chance to check my schematics yet.
