each side has a black, thats your ground.
on the right side, the dark green wire is your 12v flasher
on the left side the chocolate wire is your 12v flasher.
the common color wire they both have is your running light, tape that off, fold it back, then tape it off again to keep it out of the way.
so you take the old signals off, cut the wire, strip, attach the red wire of the zeta led to either the dark green or chocolate depending on what side, and the black to the black.
after you take your old signals off, those upper triple tree pinch bolts should be torqued back down to 17 ft.lb
hope it goes well, let me know if you need anything else
