For connecting aftermarket dash gauges to factory 3rdgen instrument cluster harnesses.
Not a fan of irreversible modifications, plus, I like professional-looking installations, so one of the goals for installing my new Speedhut gauges was to NOT hack up my car's wiring harness. So while studying my owner's manual, playing with spare factory plugs from junkyard 3rdgens, and sorting out the connections, I did a web search for something plug-n-play. I didn't expect to find anything, but there it was, from Newrad Solutions: GM 14-pin plug-n-play dash connector kit for 3rdgens.
In the third pic below, I didn't snap the GM plug into the connector because it doesn't look easy to disconnect, so the plug is just kind of resting in there. But when the plug is pushed into the connector all the way, those little "ears" on the connector will "snap" over the ends of the plug to secure the connection.
