Good evening to all. I have an issue with trailer wiring on my 2015 Goldwing. I have installed a trailer hitch and the plug and play wiring harness for the Goldwing. Checking the wiring with a test light, all is good coming out of the 5 wires. I bought a 5 to 4 wire converter and hook it up. I have tail lights out of the plug, when I activate brakes I get a good test. Now here is the kicker, I activate my left turn signal and get output on the left and right. When I activate the right turn signal, again I get signal out of both. Any ideas?
