Hi there I have a heat pump that is connected directly to power but i need to change it to its relay. How do connect the cables on the relay?It's pretty easy. Turn off all power, remove the wires from the relay, remove one of the screws at the base of the relay, loosen the other screw, remove the relay, install the new relay, tighten both screws, reinstall the wires like they were.
If you have an unused relay, you can use that as a replacement or you can get a new relay.
If you take an unused relay, tape off the small coil wires so that they don't touch anything. They should not be powered if the relay is not being used, but it's safer to cover each with a small piece of electrical tape.
Post some pictures if you need more help.

The two top screws are where the small wires from the control board connect. They supply 24 volts dc to close the relay.
The bottom 4 terminals are where the power wires connect.
You can see the base has two slots where the screws hold it in place.
Mark the wires and take pictures before removing the wires so that you can put them back correctly.
Thanks
