Question:

I had a mishap and need to replace 7 pin connector. I cannot get it to come off after removing 2 side screws. There is no set screw. Any advice please

Hey Stan, I did some research and it looks like all you have to do to remove the wires from the Pollak Black Plastic, 7-Pole, RV Blade-Style Trailer Socket # PK12-707E is loosen those two set screws, and the you should be able to pull the wires out like how Joe show's at 1:32 in the video attached.

Since that's not working, you will have to cut the wires from the back of the connector and re-wire the new connector from scratch. I know it's not the most ideal position to be in, but it sounds like your wires are trapped.

If there is anything else I can do for you, please feel free to drop a comment and let me know!

Hey Stan, how did things go after you cut and re-wired the new 7-pin connector? Your update could make it easier for others stuck with a connector that won’t release.
