Today’s job was to get the inside harnesses done. To review, I was waiting on being able to route the coil pack and crank sensor harnesses from the engine bay back tp the CPI ECU. I pulled those through a few weeks ago, but had started working on other FWF stuff before deciding that it made more sense to finish the harnesses inside; that way I’d know exactly how much slack I had to work with to route stuff around the engine.
So I started out today by finishing cleaning up all the avionics I removed a while back, and reinstalling it all. Technically I only needed the ECU, but I kinda figured I’d do a better job with everything in place, so I just went all the way. Then I dug out the CPI manual and installed the various pins into the appropriate plugs.
That just left the part of the job that I (unironically) really enjoy: lacing up the harnesses. This is one of those things that you’d think would be tedious, but I just get sort of Zen about it, plus it’s satisfying to watch unorganized forests of wire turn into nice tidy harnesses. Now this entire area near to top of the right gear tower is done:
Well…mostly. It’s not technically electrical, but I do need to route an engine vacuum line to the ECU as well. I have a bulkhead fitting to install in the firewall, and I’ll need to also add a hole through the gear tower for that line. I imagine I’ll route it alongside the harness here, but not quite sure how. Lacing probably isn’t a good idea, as it’d probably kink the vacuum line and cause a problem. I might just break down here and use zip ties, even though they’re not my favorite thing. Gotta think about that one some more.
