Like the title says I have a few plugs that wont come apart it's like they are Superglued. One of them is the main plug to the Link computer. I am pushing the release and if I pull any harder on the plug I'm going to rip it out of the computer.

Most likley because of the rubber seal. Is it in an area where it get's alot of heat..
That's a tough one.. May have to "crack" it open with some pliers and redo the plugs..
Maybe put a heat lamp on it for several hours?

Maybe disconect the Battery and try some type of lube or spray. Then some contact cleaner after you get it a part to clean up the lube.

Try tapping it lightly with the handle of a screwdriver to try to dislodge any sand stuck in there. WD-40 wouldn't hurt either, while trying to rock the connector.

Try lubing it and pushing the conncetor back together again and then apart again.

be careful with contact cleaner, some brands will melt the plastic espically the type with 111 tri-chlor , use a silicone base, non conductive cleaner lubricant.
