2012 Vulcan 1700 Classic
I've replaced my rear turn signals with ones from a 1600 (easiest way to get clear lenses). The harness connectors are not the same, so I cut the ones from my original signals and put them on the new 1600 signals, matching the wire colors. Now I get the 4 way flashing when signaling in either direction. When I disconnect one side, everything works correctly on the other side. All bulbs are incandescent, so I don't get what's going on. Any suggestions?
