I started to lay out some of the wiring. I wanted to get the PCM harness installed in the cab. I already drilled the hole in the floor and installed a grommet. Now I have to cut the carpet and feed all the harness wiring through it. The PCM and fuse/relay box will be under the passenger seat. I have a Blazer tilt bracket for that seat, so it will be easy access to the PCM and OBD port. I thought about running the OBD up under the carpet to a location under the dash somewhere, but I think I'll just leave it under the seat.
PCM harness and cab wiring harness.
Getting ready to route PCM harness.
PCM put in place and harness routing completed.
PCM pretty close to Blazer tilt bracket, but it should fit.
Test fit the seat and console in place.
