    It`s better to be silent and thought the fool; than speak and remove all doubt.

    clamp the A419 temp sensor on with the TX bulb and it gives a good visual on suction temp for future use, that only works good with gas defrost though, if you have electric you'll have to mount it where the old klixon was.

    This could be in a True box. Check out Johnstone part# B14-712. The 37T23 crosses to this.

    If you need to bypass it (temporarily)...

    One wire is the common or hot, one is to power the fans and the last one goes to the "X" terminal on the clock for termination.

    Just disconnect the termination and tie the fan wire to the hot wire.
