I have a 2008 flhtcuse3 and i decided to replace the headlight with the new Led lamp. The led lamp has a 3 prong male connector on it and when i plugged this into the existing female connector on the main wiring harness, i had to unplugged the circut for the stock headlamp. This unplugged circut also fed the garge door opener. I called the local dealer to see if they sold a adapter for a plug and play installation, they informed me they did not and i would have to cut and splice the harnnes for the garge door circut. Didn't like this idea, so i found a company which made this adapter for me. See the link provided for this info.http://www.headlightplugs.com/ . I talked to Joe and i received the adapter in 3 days . Great service and support.
