LS1 in a 72 Wiring Harness Help Me If You've Done One Before?
I'm just laying out my stand alone harness for my LS. Can anyone tell me the best place to run the wires inside the cab? I don't need anymore holes in the firewall. If you've done a swap before please let me know. Pictures are always appreciated.

I used the clutch linkage hole and mounted the ECM on the brake support.

Are you putting the PCM inside the cab, or just a few wires for gauges and ALDL connector?

Bucksss- Where did you get your grommet? I can't find one anywhere and where are you guys mounting your computers?

I want everything in the cab and tucked way up. The clutch linkage hole is a good idea. I had it marked for filling but it might finally serve a purpose. Thanks for all your input.

My grommet came on the PSI harness. I am currently building a mount that will be in the glove box area.
