Where Can I Find The Pcm On The Av  ??

I don't know about the 8.1 but the 5.3 is located in the engine compartment forward, drivers side above the frame and behind the radiator. It is behind a black plastic cover. It is aluminum.
 
kjempen,

I don't know if you are really looking for the diagnostic port/programming port, but if so, this is where it is:

Sitting in the driver's seat, look down at your parking brake. Attached to the bottom part of the dash is a port with five pin recepticles. This is where you would plug a diagnostic tool or a computer programmer. Hope it helps.

Boo.
 
Tha 8.1 has the PCM in the same spot as the 5.3 l

Doesn't seem to be the ideal spot if many water encounters

should be interesting over the years of use??
