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.

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.

Verdad Gallardo 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.
$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.
