So I bought my old 88 Sport back and i am swapping in a 351W with 4R70W. Now the guy before me took the efi harness for himself so he could swap it into a non efi car. Now with my build I am going to use the aftermarket EFI system and trans controller. I have used this unit on my wife's car and it is awesome. My question is, how do you hook up all the gauges to make the dash work? I see a couple plugs that were part of the factory efi and just want to make everything work properly.
I don't have any input but want to follow along on what you discover. What EFI are you going to use? Does that manufacturer have any suggestions?
Someone on here had a link in their signature with the factory manual for our year cars. Not sure if it was TC only but may be worth hunting for.

These wire colors may help.
