i have a 99 silverado and i ordered a tune for it but idk where the computer is located on these trucks. i have searched around but didnt come up with anything.

 

Look next to and down from the battery. It has two big *** plugs w/wires and a plastic cover. Once you find it you will laugh at how you missed it.

 

haha i figured it was simple but i didnt look much. i figured it was under the dash or something. thanks alot for the help tho!

 

this is the 4th new post ive seen asking this in the last two days, are these things running and hiding from people or what?

 

hmm, thats weird. ive been checking the forums the last couple days and i havent seen these posts. im not very familiar with a silverado engine bay and the computer is not in the open like it was on my trans am.

 

heres a 3 day old one,plenty more with a quick search
