7 pin connector

   / 7 pin connector #12  
As I am prepping my big trailer for trip in a few days, I get to revisit my connections. Conduit is a good idea, as
are soldered connections. I have no good solution to storing my 7-pin plug as the trailer lives outside. This
trailer has electric brakes, so the connections have to be good to pass the high current needed.

My other trailer has no brakes, but I did convert it to LED lights. That is also something that can help as the
lights take much less current.
Put a covered socket on both ends and use a coiled cable. Little more up front, but I like it better.

My problem on infrequently used trailer connections is usually the 7 ( or 3) brass connector pins/holes. I can usually wire brush the pins but it would be nice to have a little brush that would fit inside the holes. Kinda equivalent to a battery cable terminal cleaner.

Next time you're at WalMart, go to sporting goods and get a .17 caliber bore brush.

The 7 pin round with round connectors is a better plug than the 7 pin round rv style plug. Keeping everything cleaned off and good electrical connections is really all it takes though.

I've used the molded plugs, they can still separate inside the plug. I just use the regular screw type connectors, keep a wiring diagram in the truck. An idea to "store" the unhooked end is to mount an old female end under the tongue and just plug it in. Keeps it out of the dirt, fill it with di-electric grease and you've solved a couple of problems

I spray a light coat of Fluid Film on all my plugs. It really makes connections easier/smoother and reduces oxidation and corrosion.

Thanks to the members who pointed out that these brushes are available. Teachu2's .17 caliber bore brush recommedation will be cheap and easy to try.

Thanks for the ideas. I just ordered the brush off Amazon
