I talked with Shad @ Comptech today, and he said that there never was a blue w/ red stripe wire with the ESM, and that it was probably some other sort of ESM device. Im trying to figure out who made it.

 

Sorry to bring this thread from the dead, but I have a question about wiring the comptech esm.

The only electrical connection I found with the above illustrated wire colors and pin locations was the 3rd connector going into the stock ecu. It is the connector closest to the front of the car. I wired the esm into this connection per the diagram.

Does anyone know if this is the correct location?

 

It is the 31 pin connector. I think you are right that it is the 3rd connector (It's been a while and can't remember).

Here's a better diagram that I made.

 

thanks^^^

anyone know for sure if it is the 3rd connector in the ecu, closest to the front of the car?

 

Yes, it is the connector closest to the front of the car (the only BLUE plug in the MAP sensor)

 

yep...i did it right, thanks! dyno'ed at 267whp on mustang dyno!

 

BUMP again,

Does anybody have the comptech PDF instructions on this? Specifically the aftercooler

Since they sold off this unit of business a year ago, they are not on the site anymore.

 

contact nate at CT-engineering.com. It's the new comptech
