    I googled and could not find any good wiring diagrams for how the 2 speed pump switch is wired. Mine is a toggle with a waterproof boot on it to keep it dry (the boot cracked after a few years in the sun). Look under the wiring access plate on the motor for the schematic for your pump.

    Thanks. This URL shows how to wire a two-speed timer - [ DEAD LINK DELETED - POOLDOC ] . I ordered a marine-grade, high-amp toggle switch & boot that should be arriving any day. I'll either need to drill a hole in the rear cover plate on the motor or wire it remotely somewhere, perhaps in the timer box. Wiring appears to be straight-forward: one 110V leg to the common terminal and the other 110V leg through the switch to either the high-speed terminal or the low-speed terminal.

    I just wanted to follow-up on this thread. My new two-speed motor is in! I decided to just drill a hole in the motor cover plate and install the switch there since I won't be changing speeds very often - only for cleaning. Wiring was a piece of cake and everything worked fine on the first try (left me a bit suspicious)! Thanks all!
