03 Denali DBW question
 

I pulled a 6.0/4l60e from a Denali that is AWD with red and blue ECU connections. This Denali is DBW.

I swapped the transmission for a 2wd 4l60e
I’m looking for a harness with Red and blue connections for ECU that would be DBW but only finding DBC available.

Am I stuck reworking my own harness?

Re: 03 Denali DBW question
 

I think you must have the year wrong. The blue and red harnesses stopped in 2002, so it is most likely a 2000-02. They use a different TAC and throttle body than the 03-07. So if you try looking for a harness for a DBW 2002 truck you should find it.

Heading to the shop later today. I’ll double check the year. Thank you.

Re: 03 Denali DBW question
 

A 2000-2002 will have a 2 plug throttle body and an all plastic TAC, that's the easiest way to tell.

Turns out it’s a 2001 . Thanks you.
