How do I install an Add-a-Circuit to my 1997 Ford F-150. I need a new 12v ignition circuit.?

I need to add a new 12v ignition line for stereo/gps unit. However, I don't know where to tap into/ how to install an new circuit. My truck is a 1997 F-150 5.4L. I have spent the last few days trying to figure out what is wrong with my car stereo, and have narrowed the problem down to a faulty 12v ignition wire. Instead of repairing it, I figure it is easier (and cheaper) to run a new line from an Add-a-Circuit kit. Thanks! (And all fuses are tested OK, so I don't know what the problem with the original line is.)

1. Since a stereo can draw a fair amount of amps you do need a new circuit from the ignition switch - and you wire it to the same spot on the switch as the original line. A circuit diagram would be helpful but if you don't have one just look for the old wire connection or use a meter to check the terminals with the switch off ( no power ) and in accessory ( power ).
