In this article I will go over how you can make your own VEX connector plugs. This is useful for connecting non-VEX hardware to your controller, eg Sensors and Servos. 

==Hardware==
I am using pins and plugs purchased from Digi-Key.

*Molex Pins #16-02-0115 [http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=WM2515-ND Digi-Key WM2515-ND]
*Molex Housing #50-57-9003  [http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=WM2801-ND Digi-Key WM2801-ND]

==Tools==
===Crimper Method===
These crimper set-ups should work for all your servo plug crimping needs. Not just VEX.

*Paladin 1300/8000 or Crimp-All series crimper
*Paladin 9092 or 2097 Die set [http://technicalconnectionsinc.stores.yahoo.net/2097die.html I ordered this]
or
*Servo Crimper from Hobby Store

===Solder Method===
*Needle Nose pliers
*Soldering Iron
*Solder

==The Crimper Method==
IMO the best and easiest method is to use a quality crimper and die set. I have a Paladin 8000 crimper and a 2097 die set. The original recommended die for crimping servo leads was the 9092 set, however this set has been discontinued with no replacement. The 2097 dies look exactly the same so I am hoping the set I ordered will work.

You can also find servo crimpers from hobby supply stores.

==The Solder Method==

If you don't have a crimping tool or the wire you are using is too small you will have to solder your pins. This way is slightly more involved and the end result is an uglier but likely stronger connection. The ugly part is hidden by the connector, so the difference is not visible. However, because the pin is not as 'clean' with soldering it is more difficult to insert into the plastic housing and almost impossible to remove.

Start by stripping 1/4 inch the wire, if shielded, and laying the wire into channel at the back of the pin. Using the needle nose pliers, carefully bend the tabs down around the wire, firmly enough that you can let go of the pin and it won't fall off. Using as little solder as possible, adhere the wire to the pin.

==Final Assembly==
Once the pins are connected, simply slide them into the plastic connector. The catch tab on the pin should face the side of the connector with the square holes.

==Special Notes==
I have yet to find plastic connector housings that match the original VEX ones exactly. With these connectors you will have to be sure your polarity is correct when inserting them. Ground (black) is toward the outside of the controller on all connections.
