could someone post up a link on how to change out computer. because i got a new nelson tune and wanna put it n myself. also i need the crank relearn procedure

 

Find computer, loosen the two 7mm bolts in the harness (one per side) remove harness, remove PCM, install is the reverse of removal. Might not need the crank relearn, I didn't in my 02 (not sure if anything has changed).

 

ok appreciate man hate to sound dumb but exactly where is it located

 

You probably think that guys that put their vehicle specs in their signature are braggarts.

 

PCM is probably what you wanted to search for to find the other threads like this one.

The PCM is located next to the battery and down a bit. You'll see it. However, Knowing what year your truck is would help as i think the 08+ models are in a different place.

 

its a 2005 ccsb gmc sierra wit a 5.3 vortec

 

Then it's right next to/beneath the battery...you may need a screwdriver to pop the clips that hold it in if you don't have strong fingers...and a 7mm socket as mentioned above.

 

Make sure to disconnect the negative cable first before unplugging PCM.

 

Nelson usually provides very well-detailed instructions with the pcm when he ships them out. Did you look at them?

 

yea installed it dis mornin made a big difference n power and drivability im very well satisfied. i changen it out n 10minutes. iwill b usin nelson again
