I drove it to work today, but it's not completely done. Even though I eyeballed the flanges, I found out they're different, so I'm drilling the 1/4" steel laying on the ground with a hand drill. I've got one more to go.
The controller is done, but I need some connectors. It will be locking and unlocking tonight. I originally planned to have the in-cab light flash while locking and unlocking, but the bulb isn't enough to make the flasher flash, so I'm skipping that feature for now. The controller has leds for locking, unlocking and locked, as shown in the circuit, as well as a test switch you can use to lock at the controller under the hood. The big relay is for my driving lights. This was a clean place to put it and the two circuits share a fuse, hot power and ground for less owner-installed wiring.
Inside, I installed a 2nd hazard switch for lock and unlock. The "Fasten Belts" light comes on when it's locked.
That's it for now. We're going on a big trip tomorrow and I'll report back if it all works, or if I leave it on the side of the road somewhere.
The brakes kick ass for sure!
