I fixed my switch on my Rainbow SE but one of the wires were off when I opened it up, I don't know where it connects. Is there a wiring diagram somewhere?

The details are here... Switch D4 and below...
Factory OEM switch for the D4C SE (Special Edition) and D4C model Rainbow. This switch first came as pictured in the early version D4C that came out in 1986. Rexair then changed to a new design switch that did not have wires attached. The new version had six holes that you would stick the wires into. Inside each hole was a spring loaded catch that held the wires in place. Over time, the factory found that this was an inferior design and went back to the four wire system. If you have the previous design that has six holes, below is how you connect the four wire system.

• One black wire from the switch and one black wire from the power cord makes a double connection.

• One black wire from the switch and one white wire from the power cord makes the second double connection.

• One blue wire from the switch and one black wire from the field and one wire from power nozzle receptacle makes the first triple connection.

• One blue wire from the switch and one black wire from the field and one wire from power nozzle receptacle makes the second triple connection.

You can find a wiring diagram here, Rainbow changed the switch and this is how you wire in the new switch.
