Working through my backlog of tech debt, I arrived at the electrics on the GTO last weekend. I've added 6 relays over the course of the last few years. Three for the three separate electric fans (two ECU-controlled, one AC clutch controlled), two for the headlights (high and low beams), and one for the brake vacuum assist.
They'd just been hanging out in the space between the battery and the fender. They've gotten progressively worse behaved with time, so I figured it was ripe to fix them in a more permanent way (because there's nothing more permanent than temporary wiring that works).
So I whipped up the relay holders in CAD, then printed them up, and mounted up the sockets for the relays there.
Then I whipped up a plate in CAD from a spare amazon box (cardboard aided drafting), and plasma-cut it out of some 16 ga sheet, and built up the relay board with proper plugs.
I'm almost at the point where I get to test it, all I need to do is make the pigtail that goes from the fuse block to the 6 pin deutsche connector, then test all of it, take it all back apart, and paint the plate, then install it.
The panel fits in next to the battery, and the relays will be hidden from view.
