Then, if your "light" has a switch, I'd connect the rig hot (not ground) to the wire that is switched, and the other light wire to the rig's ground wire. I never trust striped colors on wires - I always use a VOM to check and ensure correct and safe connections. Good luck!

On the fixture the outer case should be connected to the ground and the center button should be positive. If the fixture has a switch the positive should go to the switch first not the bulb. That is the jist your fixture may vary. 2001 F150 SuperCrew 2006 Keystone Springdale 249FWBHLS Send a PM if I missed something Dennis M M • View posts Geneva, IL Senior Member Joined: 11/06/2004 View Profile Good Sam RV Club Member Posted: 07/29/10 07:23pm Link  |  Print  |  Notify Moderator You don't even need a multi-meter, you can check it with a test light and see which wire from the source is hot, then hook that wire to the switched side as the others said.

If the polarity is reversed won't the light bulb suck light in instead of radiating light?
