Help me evict my 2012 precedent electrical demons

[mtnjpn]

Background-
2012 Club Car Precedent. Ran fine, new batteries etc. I can never leave anything stock so I ordered the plum quick executioner motor, an alltrax 500, upgraded wiring etc. Aftermarket charger. OBC gone.

Could never get get controller out of 1 green 5 red blink error state.
Sent it back had it tested, it was fine.
Reinstalled it, same issue. Called tech support and he had me run a wire from small - soleniod to B-. Controller works. Car runs, key works.

Issues: When I turn the key on solenoid kicks on. Is that normal?

Lights - Lights seem to have power all the time even if it is in "tow" mode.
Except when I turn the key on, lights go out and will not come back on until key is turned off.

Please help, I cannot find anything useful so far. I leave for the beach in 2 weeks.
