Silverado 2006 HD2500 = DBW?

Was the Silverado 2006 2500HD a DBW or DBC from factory?

Bonus question: does the TAC (integrated in the pedal) connect directly to the TB or is there interconnection through the ECU?

I can't find a 6 pins connector on my harness nor any DBW indications in my ECU schematics

Thanks CattleAc

I followed pin 15 from Blue Connector. That leads to a Delphi connector with 3 wires while a TAC module for a 2005 Silverado has 6 pins. What's wrong here?

Your throttle pedal assy, "APPS" should have wires that go to the "TAC" module.

The TAC module should have wires going to the electronic throttle body, and the PCM.

Crude drawing...

What color are the 3 wires?

There should be three wires you don't need that are for the cruise control. Grey, Grey/Black, Dark Blue...

I don't see any wires with that color for the drive by wire wiring.

Would you have a picture of what your working with??

If that harness come from a 4x4 truck that would be your 4x4 front diff pigtail. Not needed on a 2wd swap.

Which is a truck TB. It has 3 holes and fits my LS1 intake.

Now I need to order the matching pedal/TAC (2003-2005 truck pedal), figure out the wirings and that's it I guess?

You're mixing-n-matching components. It doesn't work that way; too many variations from model to model. Use the components for your PCM.

I see they changed pedal/tac/wiring from 2006. My PCM is 2006 so I should order 2006-2007 pedal assembly

And my TB will probably useless as it's a 2003-2005 model
