One bite at a time. Got the fuel injection harness sheathed, routed, and plugged-in (except for the fuel pump and main power). Still need to mount-up and wire a couple of fuse blocks for the new accessories near the ECU (one always hot and one on keyed power), but that’s for another day.
I’m hoping that stray red wire in the top pic (connected to the Duraspark plug) is a keyed power lead – if so, I’ll run it to a fuse block for keyed power accessories (and the bundled-up ‘Ignition’ wire for the ECU). I believe it’s “13F,” with the light blue being “14” on the main harness – so both should be keyed power, if I’m right.
