Tired of bad 7 pin connections

Is there a better upgrade to the 7 pin flat terminal connectors. I'm tired of loose and bad connections. There should be a better way.

How about the old style round pin? The flat pin was invented by the same SOB who came out with plastic headlight lenses, corn liquor in gasoline, etc. Sal.

Semi Trucks use the 7 pin round connectors. Truck stops carry a lot of parts.

Tired of bad 7 pin connections

My suggestion would be to switch over to the round 7-pin connector typically utilized in the trucking industry. I purposely ordered mine from a supply source that catered to over the road trucks to be certain that I was getting heavy duty units. With my most recent conversion, I went with Dell City and the product appears identical to what I purchased at the truck specialty outlet. The following components are what I purchased for my Overlander:Good luck with your investigation!


P.S.: I have used this setup for four years now with excellent results. The tow vehicle end hasn't had to be disassembled and cleaned nor has the trailer end . . . that was an annual task with my old blade connectors . . . and the connectors often had to be replaced after the third year with the blade-type on my vehicles. The pin connectors are still trouble free at four years. I will probably disassemble them this year just to verify that all is well internally on both units, but I don' have any reason to think otherwise.

The problem I used to have was the fact that the connectors on the trailer cord would corrode with lack of use. I used to spay some electrical contact cleaner on them occasionally to keep the corrosion from forming on the copper contacts. Since I've moved to inside storage the corrosion problems have pretty much gone away.
