If anyone cares, the parts came and the ‘assembly’ is an assembly. All switches, screws, and wires included. Surprisingly cheap considering. Plug and play other than the ridiculous “wiring harness” zip ties along the way. Slid the tank back and cut some ties to get to the 4-wire plug connector and it wasn’t too bad I guess. Guess I’m mostly mad I didn’t have longer black zip ties and had to use opaque white.
Now to go back to the same place and see if the MF’er wants to try again when I’m watching.
