look for plugged holes..

Most all GM trucks have a few extra holes punched in the firewall,and have rubber plugs in them--you poke a phillips screwdiver thru the plug,it then becomes a grommet!--or you can yank it out and run ALL the wires thru.them put something like a slit hose to prevent them from chafing on the sharp metal and shorting out..the plugs resemble a male sex organ,they are installed from the inside of the cab,only a small "nipple" sticks out under the hood side...I used the ones closest to the gas pedal and fuse box most often..

most of that stuff would be better to run off ure fuse box. it has extra spot for acc. so nice and fuse for ya.
