2002 TACC modules are all plastic, IIRC. Yours is likely a 2003-2005 as it's got a metal mounting plate. They are not interchangeable with the throttle body you have as it ooks like a 2002 Vette TB. PCM, TB, TACC module and PCM file must all match. Mis-match the parst and it will not function properly.

i started with the painless 60219 which is a truck harness for ls1 auto. I converted it to a m6 harness.
I am working with efi connections and he is insisting it is a vette pedal with a truck app sensor reloacated? but here (http://www.chevythunder.com/drive_by_wire.htm#1997-2005 Corvette, 2002-2005 Truck Connectors) it says its the same?
so all i need is a tac now?

many options. That is a vette TB, and cannot be used with the throttle module from a truck.
You need the wiring from a vette and the 512 MB ECU with the vette software. That's why I asked if you have any wiring.
Or you can change the TB and re wire your wiring harness, add the TP and IAC sensor. TB from a 2002 Camaro or a 85mm after marked and a tune for mechanical TB
Or you can use your TAC module and pedal and add the 1mb ECU from a truck and add the electric TB from a 03 Tahoe.
This setup will also support the new LS7 TB with the X-Link. Ls7 is the 4 bolt TB and is cool if you planing to do some upgrade and will of course suport your use of cruse controll.

It is the 1 MB ECU you have on the picture. Do you have the wiring from the pedal to the TAC and from the TAC to the TB?
Take pictures of all your wiring and post them.

pcm is from a 2001-2000 ws6, trying to find out now for sure. engine came with a cable throttle body
pedal and tac were supposed to be from a truck... same truck... but i will pm the guy
i used a painless harness since i got it at a good deal so it came with the pedal and tac wiring. everything just plugged in.
the pedal i have i shortened and moved the mounting tabs, so incase it looks different. the number om top of it read-- 9700136958 and a barcode
can i just get a vette tac?

You are definitely working with
- 2003-newer truck TAC
- LS1/LS6 Corvette throttle body
- Corvette pedal
The connector for the pedal is wrong for the Corvette pedal, so I originally suggested you may have a truck APP sensor installed on the Corvette pedal. But after seeing the picture of the pedal connector...
...someone slotted the truck pedal connector to be used with the Corvette pedal. In other words, you probably have an original Corvette pedal (not modified with truck APP sensor). So if you get a Corvette TAC, you will need to be sure the TAC to pedal harness is wired properly.
