Mine is DBW. TrailBlazer pedal. I believe the TAC module is from the same vehicle. It was plug & Play with the CPW harness. Cruise works fine.

This is the bracket Harley made for the pedal. It will not fit 98+ I believe. Even then we had to tweak it a bit and bend the pedal towards the hump.
![348327]()
This was the aluminum prototype with the pedal attached. The final version was powder coated steel.

I'll have to take a pic of the TAC module tomorrow. It fits where the current cruise unit is, and even uses the same holes. @Harley an explain how we got the wire harness for it thru the fire wall with a grommet to seal it.

In this pic, you can see where the wires come thru the firewall in a grommet just above the cover.

TAC module controls the cruise functions with the DBW throttle body. If you're getting a custom harness made all the connections should be where they need to be for it to work. When I talked to CPW about @Rhotpursuit harness I did tell them where I was mounting the TAC module and they provided the wiring where I needed.
I'm trying to remember why the 98+ is different for the pedal mounting, but I think it's just a slight hole position difference. I could, at some point, mock up the difference with my 2000 and develop a bracket for the 98+ too, but not sure if my price point for selling it would be worth it to anyone.
I like to use the 03 Trailblazer pedal because it works with the 03 era full size truck TAC module and is plentiful in the junkyards. The full size pedal doesn't mount as easily, so I avoid them.
![348336]()
The other pedal I like to use is the GMT400 Diesel pedal. They are close to mounting up if they don't directly. I made my own bracket for my own reasons, but it was also easy to do. The only 2 caveats with the diesel pedal is the wiring is close, but not exactly the same as the full size pedal and I recommend a travel stop to make sure the sensors aren't over-travelled. I had that issue until I added the adjustable stop.
I used the full size pedal harness for @Rhotpursuit truck. The Trailblazer pedal has a different connector, so I had to wire that in. The harness was routed through the S10 throttle cable hole, but I had to open it up. I used a lathe to make a centering bit the size of the original hole for the hole saw, so that it didn't wander. It worked better than I thought it would

Thanks oldeerslayer & Rhotpursuit for getting back to me with the pictures and info I will take all the information I can get on the doing this swap. I picked up the 5.3 today had to wait 3 days for them to pull it out.
