Not sure if you have a HS or HM but if you have a Strada, you should have two outlets. If you have a Tard, you may be out of luck. Have a look at this image out of my 2016 HS owners manual. Notice the box marked 'C'. It shows you what you should be looking for. Now do a 'Where's Waldo' and find the letter C on the pictorial of the bike. Hard to find but there is one near the riders leg and the other under the passenger. Both are on the LH side. Cheers
