Have 2014 Triglide that I bought a 2004 bushtec trailer to pull. I bought the wiring harness for can bus wiring a year ago. Then the hitch. Got it all installed. Now I had to wait to save up money for the trailer a friend of mine was selling.. Got what I wanted and now I hook it up. All running lights work. Turn signals work. Then I applied the brakes and the right turn signal light and brake light comes on. No blinking just yellow and red light. Called Bushtec and they say I might need a new isolator replacement. I thought, does those things bad? they are a sealed unit. They asked how long ago did I purchased the harness and no warranty. The harness was mounted under the seat so no heat and pretty protected. Any advice would help. Bushtec did tell me that their tech was out and can call tomorrow, But the person I was talking to was trying his best to help.
