I just installed the license plate bracket with the aux lights.....it has a long wire with the 4 prong plug, but only two wires in the plug....directions state to plug into the four plug Duschue (spelling) plug under the seat..I removed the seat, didn't see anything, removed the right side cover and there is a plug that the tail light plug will fit into. however when plug into this plug, the lights don't work.....main blake light still worked, but not the aux lights....

Is there another plug I should be looking for?????

Thanks All

Bike is 2007 Classic

 

You plugged it into the diagnostic port for the ECU.
The plug may be used already if you have the LED spoilers or the trunk may have used it. It should be right in front of the battery
