I ordered remote control hardware from Amazon https://www.amazon.com/dp/B07P2G4T22?psc=1&ref=ppx_yo2ov_dt_b_product_details and initially installed module behind the switch panel and wired it into the winch control switch. After researching the 2014 HiSun service manual posted by another forum member, I discovered a better way to implement (fyi-this is not documented any Coleman service manual that I could find) My UTV is a 2022 model, but the wiring appeared to be the same for my model.
There was an unconnected Molex plug hanging under hood on the driver side (Molex#33471-3301), (see photo). I purchased a Molex 3 wire connector ((Molex#216283-1032) directly from Molex for $5.82 including tax & shipping. This connector has the 3 wire pigtail to easily splice to the remote control module wiring. https://www.molex.com/molex/products/part-detail/cable_assemblies/2162831032 .
I added a ground stud near the parking brake mechanism in order to connect the black wire from the module see photo) . I added velcro to the module and then secured with zip ties to the back of the nameplate bracket (see photo).
See the wiring diagram for hook-up that I used. The loose blue wire is the antenna so it is not connected to anything.
