[michael bustamante]

cru_zn. thats what iu like to see.. nothin... lol
I like that idea. running everything under the dash. i take youi installed the fuse box after you ran the wires thru the firewall?

[cru_zn_29]

Yes

My computer is mounted behind the gauge cluster and the harness goes through the firewall below the intake so it's barely visible. The fuse box will be under the dash as well.

very clean!

What is the rubber wire flex-conduit from?

I mounted the ECM under the dash mounted to the brake pedal bracket. I used the hole that was for the clutch linkage for the wiring harness. It is the factory length harness.

My Blazer has a factory 67-72 auxiliary battery tray, but I have cut the right side ones apart and rewelded them back together the opposite way to fit the other side before. The auxiliary tray is easier if you can find one though.

I don't have a part number, but i just measured the o.d. of the harness and the i.d. of the hole on the firewall and ordered several close sizes from McMaster Carr. They are cheap. The hardest part was stretching it over the ECM connectors.

I cut my original apart and swapped the sides. Thanks for the idea!
