Control Panel to Tier 3 Engine Wiring Harness

This harness works with Non-Remote, Remote JMS (yellow remote), Kartech 2 & 9 Button. See picture thumbnails for visual on which panel you may have.

If you don’t have a power pull out reel, you can install this harness yourself. First, you would need to cut the zip ties that attaches the harness to the bundle of hoses on the rear side of the jetter. Then cut the zip ties that hold the harness to the main 2” x 4” steel rail on the front of the jetter behind the engine. Then you will be able to disconnect the harness and pull it out at the rear of the jetter. To install do those steps in reverse. If you have a power pull out reel, then your jetter should be taken to a service center because it will require the water tanks being removed.

IMPORTANT NOTE: Prior to installation, we highly recommend running the harness over the top of the water tanks and testing it with your jetter to ensure that this part has resolved the issue.

TIER 3 JETTERS ONLY - Run a jumper wire test. If the jetter does not crank and stay running during the jumper wire test, then it’s likely a defective wiring harness or engine. Call our customer service team who can assist you for further troubleshooting to confirm if it’s the harness or the engine causing the issue.

It’s possible, but due to the intricate nature of this main jetter harness, we would require sending in your harness for repair at one of our service centers to determine if it’s repairable or requires replacing.
