Hello all need help. Instaling a Challenger CL10 lift. It has an overhead limit switch. This is a common SPX power unit. Opened Motor cover and it looks like the push button is all prewired with no provision to wire in with screws. I hook the black L1 and L2 to a black and white wire. But how do you wire in the limit switch wire? The limit wire is 1black wire and 1 white wire. Do I just hook the black to black and white to white with the incoming power leads. They provided 2 yellow twist caps so am I right on that.
