Hello all, new here. Hoping to get some help. We are suppose to go camping tomorrow night. I have a a/c problem. I ordered a new led relay kit from dometic and had it shipped overnight which comes with the relay box and new led thermostat. The problem I have is it did not come with any directions at all. My a/c unit is a dometic duo Therm model 59516.601 and I got the relay kit 3104998 I need to know what 3 of the existing wires at thermostat needs to be hooked up. Also the old relay box has a place where the old sensor to keep unit from freezing up can be plugged in. Can I just plug in the old one and keep new one as a back up. Then there is a place that the 4 prong plug out of old relay box will plug into new one. There is a 6 plug that only has 4 wires and no place to put it on the new one. Then there is two wires plugged into old board where it says furnance. A spot on new box where these two could be plugged in. Any help would be great. I can get more info or pics or color of wires if you need it. Thanks for looking. Ken

Yes, just B+, B- & signal wire to the thermostat.
The rest are extra and can be twisted back out of the way.

Hey, smkettner I have the same part no. On my metal box as you. 3107541.009 is there only three wires I will hook to harness. And hook the same three in back to thermostat. Are all of the rest of the wires extra? I have everthng else hooked up. I have the two wires hooked to furnace terminals. I have the freeze sensor hooked in its spot. I have the plug with the big 6 wires hooked in its place. So all I should have left is the wires that come out of the provided Barnes correct. Thanks

Not exactly the same but I think it connects similar.

I could not use my old freeze sensor as the connector was different. I would connect the new freeze sensor just in case the specs have changed.
