Cole, if you follow the wiring from the back of your rotary switch plate you will come to a terminal strip. The purple wire from the off-run-fan switch controls the a/c compressor. The red wire from the same switch thru the terminal strip controls the water pump ( either directly on self contained units or thru a pump relay box if remote compressors are cooled by a single pump ). Removing the red signal wire from the switch side of the terminal strip, and adding a jumper across the purple and red wire on the opposite side of the terminal strip will power the pump only when the signal is sent to the compressor. A single water pump with multiple remote compressors is powered from this same signal but thru a pump relay box using a trigger for each switch turning on a triac which in turn powers pump. As a reference please search www.cruisair.com click products, click DX REMOTE SYS WATER, and then select L2086 PFD. You will have a complete installation and operators manual with wiring diagrams. Page 32 (top), 33, & 34 will show switches, terminal strips, relay box, and color coding. This manual covers both self contained and remote units. Make sure this reference covers your application.

Thank you very much Frank! I was hoping someone would know the wire colors, that makes it easy. I looked around the Cruiseair website and didn't find anything before, but now that I know what to look for I'll go get that manual.
