i have to some how conect both wires from the female to the male on a mother board.

Its for the power led on the front of a case. a light thats needed by the user to know when the computers acualy on.

if one of the 2 can be moved on the same conecter i rather that but i was pondering introductions to an exacto knife. but thats a last resort. i figured i would ask others see theirn opinions and solutions

they're often like that. case makers and mobo makers need to get together more often. those led's need correct polarity. try reversing the connector.

what's the mobo maker and model?

His issue is three pin connector where only two pins exist on the motherboard. Reversing the connector won't work as it still won't fit.

Easiest solution:
Find a (spare, ie; from another unused machine) two pin LED connector with wires in it, cut the three pin connector off and splice the wires. If the LED doesn't light, then rotate it 180 degrees.

Harder solution:
If you can't get your hands on another connector, using a pin, you can "collapse" the flat section of the actual female metal connector in the housing and pull one wire. Then cut the connector housing down to two "slots", carefully bend the flat section back up and reinsert the female connector into the "center" housing slot. This can be tricky though, sometimes that flat section breaks from the bending. But if you're careful, it can work.

So what do i use to shave it down?

I use an "Exacto" saw, part of the Exacto line of "modeling" etc tools. It's blade is about 6" long, .625" high, and .006" in thickness. Very thin fine toothed blade. It's like a miniature back saw.
