You will need to delete vats from the PCM file. Then all pink wires will need connected to switched ignition, orange wires from PCM go directly to battery constant power. Then add the 2003-2005 tacc module with the alluminum back plate and truck pedal. That's it for electrical systems. Then it will fire and run. Then add the 02 sensors etc.

Go here for what wires need deleted from a green blue PCM.

Pretty simple.

Joe Lluvia Avila

Good enough. Thanks!!

I can just plug those wires into my existing fuse box and be good to go?

As long as they are fused you will be good to go. Note you must connect the purple tcc wire so it removes 12 volts when the brakes are applied. Generally I use a mid80's gm 4 wire brake pedal switch.

Ill be switching over to drive by cable system. Do you have a write up like the one you sent me for 99-02 body or 99-02 pickups/suvs??

Yes I do but why switch? DBW is neat as it includes cruise control and you already have the throttle body. Works fine on all the corvettes with Lsx engines. Pm me your email and I can send you a spreadsheet.

Joe Lluvia Avila

You think I have a better advantage staying DBW? I can get pcm harness, pcm and throttle body for $200 or pedal assembly and taco module for $225.

Thanks for the info. Im going to go thru this soon myself.

$225 is too much $$ for a pedal and TACC. You should be able to get them both used for around $100 or less. It' be easier than buying the IAC and TPS pigtails and adding the wires. I prefer DBW.

Chk your email for the 99_02 spreadsheet.

What vehicles pedal assemblies would compatible with my setup? Engine/tranny and harness came out of an 04 tahoe. I don't know if it was a ls, lt, lx.

Joe Lluvia Avila

Found an 03-07 tahoe pedal and tacc assembly on eBay for $140

Joe Lluvia Avila

Got your email. Thanks akanovaman

Fair price. Be sure it includes the jumper harness between the two. Comparability depends on the PCM service number.

Joe Lluvia Avila

It does not include the jumper harness.
