I got an OEM light switch from the junkyard with plans to wire up some aftermarket fog lights. What I want to happen is when I turn the switch one click the 2 lights on the bumper to turn on, then I turn it again and the 2 lights on the roll bar to come on with the bumper lights staying on. I need to figure out which wire does what and where they go. Or is this project too advanced for an average joe? Thanks in advance!
