Well, typically most connector pins are stamped out from sheet metal, folded and pressed into shape, and crimped on the end of a wire with some god awful expensive tool (hand crimpers can be $300-600 a pair). How the pins are retained in their respective sockets/plugs is there is usually one or more tabs that were pressed out the same time the pin was stamped. Pin goes in hole, tabs stick out, tabs grab sidewalls of hole, pin is stuck. The only way to get them out is to use a special tool that you can slip in between the outside of the pin and the wall of the hole its in.

Fortunately they are easy to make out a bit of spring steel. Yeah thats right you just got to about use spring steel to make one. I made mine out of the wire clip that holds a motherboard northbridge heatsink in place. I was gonna take a picture of what mine looks like, but basically the idea is to put a 90 degree bend on one end of it about the width of your finger so you can get ahold of it for inserting (ok more like force) it into the pin hole. On the business end you will need to make a slight bend downwards and then take a grinder, either a bench grinder or dremel tool, and carefully grind the spring wire flat to the depth needed to reach the retention tab leaving the bend you made intact. Be careful you don't heat it up too much, otherwise your tool will lose its temper and won't work worth a damn. The best way to visualize it is if you were to take a hypodermic needle and put like a 10 or 15 degree outward bend on just the angled point part (which that might work too). The idear is when you slip it in, the "tool" will make itself flat, but as soon as it reaches the tab the droop will want to spring back down pushing the little metal retention tab towards the inside of the pin where it will stay. Then you can just pull the wire out like its nothing.

Actually after googling check out the HTA tool in the background of this pic... thats how you want to make your wire look.

I don't know if pc tools will work for that plug but here is a source.


http://www.performance-pcs.com/catal...ducts_id=36094

That's the kit I use for PC repair,

http://www.performance-pcs.com/catal...ath=60_143_272

The page it is found on w/ more crimps and extractors. If you need to purchase from them Performance PC's is an ok bunch. I've done business with them for many moons.

Worst case go to a boneyard and get the whole plug.
