So I plan on swapping in a TPI for my 88 TBI utlizing an EBL with my TBI ECM (BobR from dynamicefi.com says it will work).

I know that I need to add in the 6 extra injectors, and that the TPS and MAT need to be modified, but what other sensors do I need to add into the harness to make this work?

Also, if I do need more sensors for the TPI, how would i hook it into the TBI Harness with the TBI ECM and EBL?

thanks for any input.

 

I'm doing this myself. I have an 87 305 with tpi and a 7747 ecm. I moved a few pins in the connector and added a MAP sensor. It runs, but the truck isn't finished so I don't really know how well it runs. (can't drive it)

The 87 harness is batch fire, so I didn't have to do anything about the injectors. I also added a MAP sensor. I used an existing port on the passenger side of the manifold near the distributor, and spliced into the TPS wires for the 5v and ground.
