FX progress, slow

The progress on rewiring the FX has been slow. Got the old harness out, there’s some weird routing of that wiring. Got it all unravelled. Toyota electrical tape nice, it unwraps clean without sticky gunk. Slowly working out what to take out. Didn’t get much done in middle of week, was sent to the Island of Chickens on wednesday & ended up being a long day.

Wires wires

Whew, ok started the rewiring project. Here’s the engine bay as it was at start of today.

Bust out the box, check it out, was shipped in a JDM box. Haven’t bothered to figure out what originally was in this box:

So I happily pull out all the bits and lay it out on the garage floor, arranging it roughly how it would have been in car. Looks good so far.

Start checking the connectors out and unconvering the hacked in existing ECU in the FX. The gob of silicone in place of plug is one of the things I want to fix.

Unfortunately after much searching & wondering, it looks like the new harness is missing this connector also! Curses! Crap, its going to be difficult to find just this connector.

Anyway, I start to uncover the new harness to figure out what I want to use.

I’m taking my time, pulling connector pins out & slowly getting rid of the bits that I won’t use. I decide I’m not going to use the new fuse box, although its nice. The starter relay and a mystery component & connector that look like its related is also removed. The alternator looks different so those wires come out too. Anyway, here’s how it stands just a little before I called it quits for the night.

Hopefully I’ll be ready to start installing it soon. I guess I’m going to have to live with the blobby hack for now & replace what I can. I plan to pull indivdual pins and thread the wires through the firewall to keep the wiring intact like OEM, instead of cutting & splicing as much as possible. I’m hoping replacing the hack splicing job in the engine bay will smooth out some of the engine running problems. We shall see!

Squirt n wire

Box arrived with the wiring harness to match the JDM 20V engine in the FX, and the Megasquirt ECU. Haven’t had a chance to do much else then look at box & lift it. Heavier than I expected, but when you think about it, its a healthy bundle of wire. Hey, shoo you pesky copper rats, go grab some hi voltage primaries.
