wiper problems

[coleman64]

1990 chevy crew cab I at one point swapped steering column for tilt column, wiper delay has never worked since ive owned it, ive switched delay module units and motor from another vehicle still nothing. wipers have manual trip and low and high all work but no delay. what is wrong and what can i do to test it. Iv tested the connectors at the motor and they have power. Main question is what connectors on the motor actually power it and.
