I installed a light bar that came with a wiring harness, relay, and a cheap switch that I plan on changing out later. The way it is wired up now, per instructions , is the light comes on without ignition switch on. The cheap switch has a red, and green light. The red is on always, until you turn lights on, then turns green.
If I want the light to come on ONLY when ignition is turned on, and works off switch ,do I remove the positive wire to battery, which has a fuse, and is connected to number 30 on the relay, and just tap in to something that works off ignition? Any suggestions on where, and what to connect to? I just need reassurance on what I want to do. I have a 2014 4 900.

Thank you for any help in the right direction.
