Airport Problem

I've had a Mac Pro for about five years for music, i've just tried to connect to the internet and there's no signal.
I checked inside to find that the connectors had not been connected to the Airport card, I connected them as per instructions, 2 to the top 3 to the bottom BT off and 4 off, but I still can't get a signal.
I've tried my Mac Book and I get a signal so there's something wrong with My Mac Pro, any suggestions please.

The Mac Pro was introduced to consumers Summer of 2006. Sounds like you may be talking about a G5 if you've been using it for 5 years? Please identify the model and year of your Mac. As far as attaching the antenna wires to the airport card, make sure they're on correct and that the other end is attached.

Regards.

It's definately a Mac Pro, I might have the dates wrong.

I looked at the step by step pics but it does'nt show the other end of the wires, has anyone any info on this?
