Okay thanks for the morale boost :P I'll try when I get home...it won't break if I press TOO hard, right?
No, it won't break! Use some force and push them together. Unplugging them also will take a lot of force. The pins as well as the mating parts are made from sheet metal in high speed (1,200 strokes/min.) progressive dies. Then plated and inserted into the plastic housing. This is why they are hard to mate.
Difficult to plug-in - difficult to unplug.
