Default C10/Trailblazer L33 swap

I'm doing a L33 swap from a late 2006 trailblazer into a 78 c10,
My question is since the "TAC" is wired into the computer , how do I wire
The throttle pedal?
Thanks for any help

You want the tach box, gas pedal and wiring in between them. Also engine pcm.

THe wires for the throttle pedal on a GenIV come straight out of the ECM. have you looked at LT1Swap? This is for a truck, but a Trailblazer should be similar. http://lt1swap.com/E38%20ECM%20Connector%20Pinouts.htm

An '06 Trailblazer 5.3 would be a LH6, not an L33.
L33 is GenIII
LH6 is GenIV

VIN code 'M' is an LH6, like he said. L33 is a GenIII, you have a GenIV if it's from an '06.
