Wiring updates. Got the brake lights working with the pedal the other day. Had to move the switch from the rear port to the front. Messy. But now the brakes light when the pedal is depressed.
Also: Headlights work...finally.
I'd originally wired them according to the build manual but that was a total no-go since I'm using a different turn signal switch and a floor-mounted dip switch. I messed about with them a couple days and finally set about rigging up a proper ganged two-relay setup I found in one of the big boxes of random electrical stuff I got from Alan.
That gave me bupkis too.
Then, this morning, I got the bright idea of tracing the wiring in that gang box and comparing it to...oh...every single headlight relay wiring diagram on the internet.
What I found was very interesting.
Turns out the guy who wired up that connector box was eight years old, and drunk. The relays were wired together as if they were mirrored, not parallel. No wonder Merklin tossed it in the box and forgot about it.
Rewired the gang box and—eureka!—there was light!
Spent part of tonight prettying that up, making the wires that go to the floor dipper, getting the stuff ready to connect to the wiring harness permanently, and pondering where and how to mount this in the car, along with the two relays for the seat heaters and maybe one more for the fuel pump (which is currently direct wired to key-on power through the fuse box with 14s...which I think is probably fine.
