3B to t89 chassis inegration

[v8coupe]

So I've never really wanted to do this, but I'm at the end of my rope when dealing with the idiosyncrasy of the 7A ECU. I'm through with trying to make this dumb thing like what I do. Time to pull the worn and beat on 7A out and slap a lowerish mileage 7At in.

Standalone would be sweet, but this is my beater so I'll settle for chipped power levels. I have a IA III+ 3B ecu and a spare harness so time to make it all mesh in my beat old car. I haven't found much good info on how to wiring this thing up so I wanted to start a thread so As I work through this mess I can post it here to hopefully help others.

Yay my head already hurts!
