Replacing factory fog loghts with leds

[Rimer01]

I got a 2003 chevy silverado im replacing the factory fog lights with led lights. The led lights came with a harness i was just wondering if i could us my factory harness instead of the one that came with the leds since my truck already has a button to turn them on and off

You can but you need to make sure the fused power in the truck is rated the same as the fused power on the supplied harness. Also make sure no resistance is built into the supplied harness. If so you will need to add the same resistors inline.
