My friend has a positive system, and he just needed to cut one wire, and doesn't need the highs on for them to flash. Thanks for the help

The question is vauge. The only thing that comes to mind is relays. I am not sure how fimilar you are with any electronics, but a relay is switch for higher currents. For example, the starter relay has the starter power wire running though it. If it were running directly from the ignition switch, ignition switches would fail very often. The relay is rated for a voltage to be switched on, and the voltage that can pass through it. Once the relay gets it's voltage, it triggers the higher voltage and works like a switch.
On my electric fan, the sensor closes when the temperature gets to 180 degrees. This would be a negative switch, since the ground is what is causing the relay to close to turn on the fan.
A relay going to an air bag compressor might be triggered with positive voltage to the relay from a switch or pressure sensor. This would be positively switched.
If I were you, I would obtain some wiring diagrams. I can't imagine too many people knowing about your aftermarket setup. Who knows what you bought.. Kits are different, if you don't have any knowledge of basic electrics, next time you should debate weather to have a professional install them.. I am afraid no one can tell you whats wrong with out wiring diagrams and a voltmeter in front of them. Maybe contact the manufacturer with issues with their product?
