Hi ! Welcome to IRV2! We're sure glad you joined the gang!
I would spray the connections with a cleaner that has lubricant, such as the Radio Shack Tuner Cleaner. Plug and unplug the connectors several times after spraying to let friction help with the cleaning!
Good luck, happy trails, and God bless!
