Hey guys need a little help
Want to run a 2 color led on my truck with the 1st color driven from the daytime running lights the 2nd color driven from fog lights.

So when fog lights come on it changes to color 2. (White). When DRL are on color 1( Amber ). So fog light takes over

Please advise

Connect ignition power to terminal 30 of your relay, 87a to LED color 1 (DRL indicator), 87 to LED color 2 (fog lights indicator). Connect the vehicle's fog light positive output to 86 and ground 85.

You can always add a suppression diode across the coil if you want (striped side to 86).
