Thanks, yeah, tons of electronics, but that's something I enjoy. Mostly.

Not sure I follow the Q. Each board has plugs on it, color-coded and the wiring harnesses are color-coded, either by wire color or short lengths of colored heatshrink, so as to identify them.



Right-hand side of the ESP32 boards have alternating red and black headers which are outputs to the various actuators. Yellow and blue jumpers go from the DRV8833 motor boards to the ESP's; there's also green and black which is motor power that go to a power distro board up under the hood, regulated power. Yellow and black pairs are switched straight off the battery and go to a 7805 on each board.

That leftmost ESP board has red, green and blue-tagged wires for the underlift, and then at the bottom, behind the anodized red ESC and its larger drive motor wires, is a row of red-white-black headers for the Neopixel LED strings. Looks like at this point I only had a couple, the white and purple ones, whatever they are.

Rather than hard-solder anything, the ESP sockets have a male header next to them which is soldered straight across; that's what the blue, yellow, etc goes to. Those then can just use off-the-shelf short pre-made jumpers in many instances, repinned into larger Dupont shells.

And yeah, this was early on where I'd cut the wires too long before stringing them for good, and I ended up having to trim them and re-crimp. Did I mention I'm tired of crimping? =))
