'03 Vette Drive-by-Wire Pinout Does anyone have a pinout for the drive-by-wire setup on a C5 corvette? I'm interested in seeing a diagram of the wires coming from the pedal(9 pins) and from the throttle body. I'm assuming both of these pass through the PCM? How many wires are on the throttle body itself?
I did a little measuring of the pins on the pedal and it seems that there are three position sensors built into it. I know that other GM cars have only two and that they go directly to the throttle body rather than passing through the PCM.
Thanks!

There is a seperate module for the throttle called a Throttle Actuator Control (TAC) module. The pedal harness goes to the module and there is another connector on the module that goes to the engine harness. The module is piggy backed on the PCM.

Ah, ok. Do you have any idea if the throttle body will function by itself with just that TAC module and the pedal attached with the appropriate power, etc? In otherwords, can you cut the PCM out of the picture and have it work in some sort of limp home mode?
