Source for wiring schematics?
I'm still fighting my DBW / TAC module issue. I did discover today that I do have the correct pedal, and that it (and the TAC module) was used exclusively on the 03-04 Trailblazer platform SUVs (& SSR).
Anyhow, do any of you guys have a source for wiring diagrams. I'm looking for the attached diagram, but for the trailblazer rather than the truck. Again, has to be the 5.3. Thanks guys. |

Re: Source for wiring schematics?
It can be tough to locate specific diagrams but this shows the throttle body, throttle position sensor, and TAC. Ths is for a 2wd truck. I do not know if 4wd is different.

Re: Source for wiring schematics?
You may have to find a factory service manual for the model of Trailblazer the wiring came out of. The factory manuals for my 2K cad are two huge volumes with one that is nothing but wiring diagrams and electrical troubleshooting.
You might hit the service department of the local Chevy dealer up an see if they have one you can scan or sometimes they have them on a computer that they can print the pages they want out. Looking on Ebay the service manual peddlers want outrageous prices for them.
