and did u keep auto transmission? if so, is the tcu plugged in??

[GreatGreddy88]

yeah i kept the auto transmission and the tcu is plugged in

[onosqv]

then it can't be the tcu plug! hehe. consult port? I don't remember where those were located but that could very well be it.

Picture will clear everything up.

hmm, between the ecu and firewall... so it doesn't pass *through* the firewall, right? And it's on the passenger side? If it's a brown-ish color it's for the dash harness, that's attached a few inches above the ECU to some sheet metal. Other than that, the only other modules on that side are the cruise-control unit(and a relay IIRC), the A/T module, and a door lock timer.

I don't believe it's the consult plug, unless it's really long(enough to reach the driver-side).
