A power harness is included that connects to a 12v+ key on power source.

Each LED tube is driven by a custom ballast with 3 wires 

           Black=ground (to a good ground source)

Yellow=turn function  (to appropriate signal wire from turn signal kit)

Red=DRL (white daytime running light with key on) to 12v+ key on ignition source

1. Locate the power harness with a fuse holder. Connect this fuse holder to a 12v+ key-on ignition source and install a low amperage fuse (4amp is suggested).

2. Next connect the black wire to ground

3. Route each wire to the front left & right turn signal ballasts then connect to the RED &    BLACK wire of each ballast. This will illuminate the LED tubes white when key is on

4. Next connect the yellow wire of each ballast to the appropriate signal wire coming from your turn signal kit. (signal kit sold separately)

(If connecting to an existing MCS Adventures kit, yellow=driver    green=passenger)
