Previous owners pretty much cut everything out. plumbing, water tank, toilet, shower and a lot of the electrical. I have installed a water tank and water pump, but mainly have questions about how all the electrical works in these things. from the breaker panel (30amp) they ran 12-2 wire to the outlets, which I then used the hots to run to switches for lights. Can I just run this 12-2 wire to a regular light switch or something and then to the pump? or do I need to use a special pump switch? I don't really see the difference... Also, all these red, blue, yellow, wires, etc... are they ONLY for the exterior lights? (tail lights, etc..) ??? They have basically two breakers for every thing inside. I am attempting to have the lights and outlets on one.. and the electrical heater, water pump and a little window ac unit on the other... too much or ok? THANK YOU!!!
