Installed the Curt hitch cap for the Multiflex tailgate today. Install was a little more of a pain than I thought it would be. I wanted this as I damaged my ‘21 AT4 gate when I got in a hurry one day and dropped the inner gate and hopped up on the step to get something out of the bed while I had a hitch installed.


First, the instructions have very small pics so hard to see exactly what/where the instructions are talking about. I found a video on youtube, but… realized they must have made a change since that video as it connects inside the inner tailgate in a different place vs at the passenger side lock in the main tailgate. No biggie.
Then, when i did figure that out, realized they saved about $0.03 making the harness
just long enough. 2-3 more inches woulda made a big difference (thats what she said…) In routing out the harness. Also, the harness is wrapped, but not all the way the the device itself or to the connector plug. The plugs were too big too slip any shrink wrap over it, so ended up just making a few wraps with electrical tape just the add a little abrasion protection in those areas.
Finally, when tightening the actually device on the receiver, it was a tad loose and my OCD couldn’t stand it, so I found some 3M double sided tape (turned out to be just the right thickness). I cut a few piece to fit inside the top and bottom part where it clamps around the flare on the end of the receiver. I left the red film on the side touching the receiver, and reinstalled it - fit perfect that time!
It does work as designed. Inner gate opens normally when the cap is closed, but does not open when the cap is open.
Pics show the device installed and one of the spots where they stopped the wiring harness wrap just a bit shorter than optimal in my opinion.
