I am replacing two motors on my CalSpa. One single and one two speed(240v 4hp)

I am also replacing the wiring harnesses. Naturally, the old harnesses (wire colors) do no match the new ones.

I want to make sure I get the new connections correct.

1. Is there a usual wire color to be hooked to the Hi, Lo and Common terminals on the two speed? i.e Red=Hi, etc.

2. On the single speed, does it matter which lead goes to each of the two terminals? The motor says it's nonreversible.

Thanks.

"normal" wire color codes:

Red = Low speed
Black = High speed
White = Neutral (120V) or L2 (240V)
Green = Ground

With the single high speed pump, if 240V, it won't matter which way you connect the L1 and L2 wires. In order to reverse a motor, the internal windings must be re-wired in your situation, so have no fear.
