I have an issue with corrosion on my truck trailer plug. The last one, replaced last year was 10 years old and corroded (blue build up) and took out the brake pin. This year I noticed the same thing has happened on the replacement. Am I correct in assuming it might have something to do with the brake controller. The controller is an old basic model and I was going to replace it anyway. What would be a good replacement?
Thanks for the help.
