No owners manual. Disconnected the safety sensors. Model 41A5021-4G. Three terminal posts.
post 1: red - w/ red stripped line from wall button.
post 2: white - w/ white line from wall button.
post 3: black - nothing now.

Have lines from safety sensors (1 line from each sensor, 2 wires each line - one w/ colored line - one is white.

Where do I attach the wires from each sensor?

Thank you kindly.

The wires from each sensor should be white and white with a black stripe. Both white wires go to post 2 with that other white wire and the wires with the black stripe should go to post 3.
