I always spray WD-40 into my 7-way connector and plug everytime I use them. Seems to work out pretty good for me.
The only reason I use the WD-40 is it is there and works on everything else I spray it on...
I will spray a couple of good squirts into the 7-way receptacle and then hook up and wiggle the plug around pretty good a couple of times.
