Not taking any chances… – The blog of Mister 4×4

After finding the ECU yesterday, I made it my mission to get that sucker mounted up before I wind up losing it in plain site again. Best place I could find for it without having to bundle a bunch of wiring harness was over on the driver side firewall where the old factory Duraspark module lived. I also adjusted the driver door striker so it would close better, and laid the wiring out loosely where it will be routed for final connection. Tomorrow, I’ll finish up the wiring … See more

The spot on the firewall I wanted to mount the ECU has a pinch-welded seam sticking up about 3/8 of an inch, so I made this bracket to straddle the pinch weld. Took about an hour of using the Dremel and my fence as a metal brake to get this.

After dropping and chasing the self-tapping sheet metal screws every time I started to drive them home, I finally got it mounted up. Soon, there will be a ‘key power’ fuse block, and a ‘constant power’ fuse/relay block living nearby for the EFI, electric ‘lift’ fuel pump, and H4 headlight relay power circuit.

I need to figure out what that stray wire is for (probably don’t need it…) and plug those holes thru the firewall (don’t need a hole for the clutch pedal linkage, after all).
