Northern Lite truck to camper cord

I had running lights, turned on the flashers they worked so I thought I had brake and turn signals. I was stopped by the highway patrol seems like every time I hit the brake the back up lights came on.

Just trying to understand this. If you have flashers working on camper, then brake/turn is wired correctly. ....the Blue trailer brake wire terminal is not used with a camper. If you are getting backup lights in addition to brake lights, then I think backup lights wire may be shorting across to brake terminal in bargman plugs and energizing backup lights when you step on brakes...probably in one of the pigtail ends, but could be truck plug or camper plug....when I wired up my pigtail I kept that blue brake wire out of the Bargman plug on the camper end and taped it back alongside the cord....are you getting any backup lights when you go into reverse?...or just when you step on the brakes?....
