Multigate Connector Difficult to Connect Fully

[Another JR]

Hi All,

I operate my 2021 3500 SLT most of the time with the tailgate off and in a crate because I have a slide-in camper. However, at least once a year, I take the camper off and put the tailgate back on. Recently I installed the tailgate, but had a hard time getting the connector bail to swing to the fully latched position. The connector seems to fully seat, and everything works, but the bail doesn’t swing to fully latched position.  It swings almost there but stops and I am afraid to push it any harder. 
 

Does anyone have any advice on cleaning or lubrication or anything else I should be doing?  i know how to properly operate the connector. During the time the tailgate and connector are off, i have a double plastic bag over the truck connector secured with rubber bands to keep it clean, but it still had some dust in it this time when I blew it out with compressed air. I didn’t want to spray it with anything other than air without doing some research. Thanks.

I had a similar problem with the connector for the ITBC on my '12 3500.  I finally got it to fully slide on and have the latch engage by putting some dielectric grease on the silicon seal.  That allowed it to slide onto the connector, instead of catching on the connector and jamming up.  I used a q-tip to just apply it to the silicon seal.
