PCM Identification
PCM Identification Bought an Lq4 for a guy on CL, said it came out of an 06 3500 (DBW, 24x). Trying to sort out how i am going to tackle my harness, but i have hit a roadblock on whether or not my TAC is in the PCM, or attached to the pedal. I have seen that TBSS and SSR's got the TAC in Pcm, so i'm not sure if that was only for limited edition vehicles or what, but either way i need to know in order to determine what pedal and TAC i might need. Was hoping someone might be able to shed some light, i found a partial list of popular PCM numbers, but i do not see any of the numbers included on my sticker on the list. Any help would be appreciated. Link- http://www.chevythunder.com/LS1%20co...Identification

search under the Flash code YKYY
I found lots of info on applications with this
rock auto has delco reman with that you can use the reman # to cross over what else that PCM or variants of came in.

RA came back with flash code YKYY fitting 04-06 silverado 1500 PCM. Did a little more digging on that particular vehicle and found the "Throttle Control Actuator" is separate from the PCM on that particular vehicle. If i did the same search using the details my CL guy told me, the TAC and PCM are the same part number for both vehicles, so i feel confident i should be able to make it work.

All DBW applications have TAC modules, that alone should tell you that it's separate from the PCM. On the trucks they should be located to the rear/upper/driver's side of the engine bay mounted to the firewall. And TAC modules need to stay with the pedal assembly if you're getting a part-out one. If getting a new one, make damn sure it's the correct one.
