BTW, I did use a multi-meter to be sure that I was supplying 240v, so I am using the high voltage wiring.

Here's the wiring diagram.

I have a new polaris pb4-60 booster pump that I bought to replace an older pump. I have everythig installed but the wiring is different tha on the old model. I have a timer with two wires, one red, one blue leading to the booster pump. Both are labeled "Load" coming out of the timer. I have the green running to the green screw. Where do I hook up the red and blue wires? One internet source says that it doesn't matter which one (red or blue) you hook up as long as you hook them up to the 240v connectors. Is this correct?
