The wire harness is an important piece of your softener for two reasons. One, it meters the water flow and two, it helps the control board communicate with the valve head. Let's get this piece replaced and your softener back to running properly!

Disconnect the Wire Harness
1. First, you'll want to unplug your power cord from the outlet.
2. Go ahead and remove the top cover. Check out Removing the Top Cover if you need additional help.
3. Now, looking down at the top of the softener's valve you'll see the Wire Harness has three connections. The red connector shown below is connected to the control board. Find the green and orange wires that connect to the Switch and remove that white connector from the switch.
4. On the back left-hand side of the softener, locate the red, white, and black wires that connect to the clip around the outlet port. Your clip may be white or black. Go ahead and remove that clip. If it's white - unclip from the underside. If it's black - unclip from the middle area in between both outlet ports.
5. Now, we need to get to the control board to disconnect the Red Connector piece. Inside the top cover, you'll notice several wires leading to the control board.
With Plastic Cover
Squeeze both sides of the shell to remove cover.
Without Plastic Cover
6. On the control board, remove the rectangular red plastic wire harness connector with 5 wires connected. Great work! The first part is complete.
Install the New Wire Harness
Now it's time to install the new wire harness.
1. You can go ahead and attach the new green and orange wires to the switch with the white connector. The orange wire should be on the outside left side of the black switch box. The front-right metal prong on the switchbox will stay exposed as the picture shows below.
2. Now clip the Wire Harness piece onto the outlet pipe. The clip will only snap on in one direction – so if you're having trouble, try to turn the clip around. If you have a white clip - the wiring should sit at the top of the valve. If you have a black clip - the wiring should sit on the side of the valve.
3. On the control board, you're going to attach the new red plastic wire harness connector. You'll want to make sure the wires are running away from the control board.
4. If you had a cover on your control board, go ahead and put that back on now.
5. Now you can put the top cover back on the unit.
6. Last step here! You can reconnect the power cord to the outlet. Nice work! You're finished!
