So im in a bit of a pickle. Long story short I have a 2019 ram 1500 with rams oem brake controller and a 2015 zinger rv. My truck keeps giving me intermiten warnings that the trailer brakes are disconnected and to check wiring after a few min of driving. The warning will go away then come back etc.... I have not had this issue connecting to other trailers, even this trailer wasnt giving this issue when i first got it. And the rv shop just called saying there equipment is saying my trailer is fine. The only 2 things he said is the trailer is working but it's signal (whatever that means) isn't to the trucks liking so it's thinking something is wrong. He also said to try an aftermarket controller. But I like the factory look. Anyone know what might be going on?
