Parallel Cable Guide?

I'm working on hooking a NES controller into a computer via a parallel port. The web-site I am using as a guide says "Use a voltmeter to test which cable matches each prong". My question is: How? Does anybody have a guide to the colors of the wires for each prong? PLease help!

BUMP...anybody out there can help me?

How about posting a link to that guide?

It's pretty barebones

It means you measure the resistance between the pins, if they're connected, it should be zero (or very near it).

HUH? What does that mean you do...I'm a bit clueless.

It means you set your multimeter (a really fancy voltmeter if you like) to a mode to measure resistance.

Then, say you want to know which wire corresponds to pin 2 in the DB25 plug. You touch pin 2 with one probe and then go through all the loose wires in the other end with the other probe. The wire that shows near zero resistance is connected to pin 2.

I set mine up differently. I used my cheap Radioshack voltmeter and attached on e wire into the meter. Then I wired a battery into the other prong on the voltmeter to a battery. Then I touched the wire from the negative side of the battery to each prong until the voltmeter showed a positive response.
