Okay, first things first:
Here are the male/female terminals I gave to
@AirheadNut to make the harness work for him. Again they came from Corsa.
Yep, that looks like the correct one. I didn't see those when I browsed 6-pin connectors on their site, and that oversight is on me. I found 106 others, but somehow missed that one...but Eastern Beaver has some on the way to me, and they'll hopefully be here on Monday. I'm going to get ready for that by doing some wire-shopping and harness-cutting; I'll basically use the one that I bought as a template for lengths and orientations, and then harvest any needed parts from it once the connectors get here. Incidentally, that connector works on wire from 16- all the way down to 22-gauge; that's pretty broad...so I'm glad that I bought some extras. I'll use one or two of them to make the harness modular, so everything can come back out in pieces if need be.
I also splurged and finally got myself a decent crimper for these smaller bits. I have three or four crimpers that I've either found or inherited over the years, but I don't really like any of them...so hopefully this will do better.
Pictured: It certainly feels crimpier than the others.
Okay, on to the updates...and the tl;dr is that the converter is installed and working. The bracket is in its final place, the power wires are run to the relay block, and all of the wires that can be loomed and/or tied at this point in time have been thoroughly subjected to those treatments.
Pictured: WAY too much Binky.
I actually took that one before the last of the wiring went into place; it was getting cluttered in there with the addition of the final ground...but it all fits with just enough extra wire-room to allow the bracket to tilt outwards for access to the things. Speaking of wiring: I decided to loom the entire primary hot lead.
Pictured: So THAT'S where I left my 9.8 alpine rope...
There's a firewall grommet up high on the passenger side, behind the glove box, with an unused section that was never cut for whatever wire wasn't run through it...so I used that. It's directly behind the batteries, it's protected, etc, etc; in other words, it's an ideal location...and it drops the wire right behind the passenger-side kick panel. I routed the wire behind the other stuff...
Pictured: This was fun...
...and then just sent it to the back, which we've already seen. The finished product is actually pretty underwhelming; it's just a wire that's cable-tied to some metal. The only visible piece is right here:
Not Pictured: 11'-4" of 6AWG
I should be really sneaky and steal a piece of early 90's OEM Toyota loom from the graveyard and snap it around the braid...but that's a bit of window-dressing for later. And honestly, it's just me being pedantic...but whatevs.
So... that's where we are. Today I'm cleaning the garage, waiting on connectors, ordering wire as aforementioned, and trying to figure out a battery solution. The current batteries are several years old, and one of them has a slight bulge in the case; I'd rather stop that problem before it gets any worse. I know Odyssey makes a high-CCA and high-capacity AGM group 27 that won't get killed by deep discharging, but I'm not really finding many more that offer the same specs. I can't find many AGM starting batteries at all, to be honest. So, this might be a fun side-quest...
