Hi my name isXXXXX can help you with your issue.
The way to wire that is the 2 power leads that went to the compressor on the original relay get tied into the power leads on the 3 in 1 and then hook up the compressor directly with the other leads.
Your unit may not have had a capacitor on it.
If it had a capacitor then there would have been a wire going and coming from it attached to the old relay.
