Can I Wire Driving Lights Using Factory Switch?

I have a '97 Blazer 4wd. I would like to wire a set of driving lights using a factory switch. Right now the spot for the switch has a blank, however when I had the dash bezel off, I noticed what looked like the factory wiring for the switch. There is also wiring and plugs at the front bumper where the lights would be. My question is, can I just get the factory switch and plug it into the wiring in place and go? Or am I hoping for too much?

If you want to control the driving lights separately, you'll need a separate switch. If you want them to come on with the headlights or park lights, you can tap into the respective circuit. Either way, you'll need to use a relay.
