LS3 PCM Location

[Zombie666]

Now that I'm at the wiring stage of my Chevelle build, my cruise and connect package came with plenty of wire in the harness and this includes the harness for my 4L75E tramnsmission. The engine also comes with a giant fuse box that also needs a home. I'm curious to see what others have done with theirs. Did you keep things under the hood or cut a huge hole through the firewall and install the PCM under the dash. I look forward to seeing what you have done.

On my 70 Camaro the fuse box is on the driver side mounted to the firewall hidden by the inner fender. The PCM
Is on the passenger side mounted where the factory ac box was.

Thanks for the photo. I did look at the same location but wasn't sure if I could make that work but I managed to stuff the massive wire harness in that void space of the fender well.

I stuck all my excess wire in the fender well too. You can kind of see how I routed it around.
