99-02 fbody pcm pinout vs 99-02 truck pinout Im doing a swap and got a computer with my engine (5.3) but its going in a 99 camaro using its harness, I do NOT have the 5.7 pcm as the car started life as a v6 car. Can I just use the 5.3 pcm no problems or are the pinouts different? (fingers crossed)

Just have them flash to a 99 ls1 and change the displacement to 5.3 instead of 5.7? What would some one charge for something like that and removing emissions and adding headers?

The Sierra did not use E-Fans, so you would need to turn that on in the calibration. Also you will only have control of one fan with the computer, as the second fans pinout is used by the HVAC. You will need to route to the A/C wire, do a search on Performancetrucks.net to find the pinout and/or A/C wire needed to tap into.
