Cleaning brush for four-pin connectors?

[RogerDat]

Daughter had an electrical connection plug on her transmission that did not keep water out, large puddles would make her transmission fail to shift. Trans shop cleaned contacts and used dialectic grease. Solved the problem.

I agree with Donna about using dielectric grease on all connections and sockets. I have been watching the prices come down on LED lighting and am impressed with the improved brightness and reliability of them. If you have to make any joins in the wiring, take the extra time to solder the joints rather than use the "instant crimp connectors" to increase reliability. You will find that electrical tape seals better if it is used when warm and flexible. Trailiering is more fun for people with all the right connections!

I'm in your camp, but be aware that others disagree vehemently
