I am just about ready to start setting up the throttle pedal assembly. The car is a 1969 GTO, engine is LQ9 with magnacharger and DBW throttle body. What have others done? I want to maintain the DBW. Pictures, part numbers? All help is greatly appreciated.

This is where I am so far.
I have a 2004 truck PCM and complete wiring harness. The next phase is pinning out the harness(can't wait for that adventure). The engine and supercharger were purchased as a complete assembled package out of a wreck with all of the electronics.
Which pedal/tac and harness will work with the truck TB?
It looks like the entire pedal assembly you have fabbed is about 12-13" long, is that about correct?

Your best bet is to go to Rock Auto website and look up the parts for the vehicle the engine/computer came from. If you click on the p/n, it will tell you wahat vehicles the APPS, TAC, TB, etc will work on.
The TAC/pedal harness was part of the dash harness on my 02 Escalade LQ9, so no way to separate it. I bought an aftermarket one.

Where did you get the harness?

philntx: Can I squeeze a question into this thread that will help me with my swap. I need to install a '03 Vette DBW pedal in my thirdgen Camaro and it will have to be modified to get it to mount on the firewall due to this large bulge for the windshield wiper motor. I am going to have to cut and weld the pedal arm also. Before I break out the security torx drivers to dismount the electronic module could you give me any insight on how it connects to the pedal pivot shaft and any gotchas I might run into? Any info will be appreciated.

Here's a shot of a 55 Chevy convertible we did for a customer with a GTO DBW pedal that we adapted a Billet Specialties pad to the arm. It wasn't very difficult.

I know this is an old post. Philntx did you cut the center out of the vette pedal and use the outer edges of the pedal to weld to a flat piece of metal. How thick of metal did you use?
