removing tailgate - 2015 GM trucks w/BU-Camera

Mine was under the bed behind the spare tire. Since my truck is lifted you can not reach it lying flat on your back and there is only room for one hand.

I took it all loose from the wire ties and got enough slack to re-mount it at the opening between the tailgate and bed when the gate is open. Now I just open the tailgate, bring up the connector through the opening (it is held by a thick rubber band) unhook it and replace the protective cap.
