PCM / TCM / Fuse box mounting
 

Doing a LS376/480 with a 4L65e in a 66 C10. I am doing a nice street/show build and looking for the best place to mount the PCM, TCM (trans control), and the big ugly fusebox that is a part of the GM Performance harness that is hidden but also reasonably easy to reach, especially with the fusebox.

I put the ECM behind the glove box. Fuses, relays, CEL screwed onto the heater box.

Another option is on the hump under the console. Of course the length of your harness could be a limiting factor.

hump may be a good idea. Don't think we will have room behind the glovebox because of the vintage air. Hope to have the body back from paint this month, so we will see. Still open to other ideas and pics of how others made it work.

Under the seat.
