Computer mounting location

[A1971Blazer]

I mounted my PCM on the core support and built a load center for the relays and fuses. While I was at it, I put my headlights on relays. All power comes to a terminal block under the fuse box mount.

this picture was during the wiring process


I fabricated a mount for the fuse box and used a modified GM mount for the PCM
on the underside is the terminal block
also used a circuit breaker for the headlights
