EZ wiring Turn Signal Wiring has me stumped.

I think it had two flashers. I wired mine per their instructions didn't have any issues. Yes I spliced their brown wire to my pink wire. Can double-check in the morning for you. How far along are you in the installation? Have you connected the other column wires to the car yet?
Make sure you have a good factory service manual wiring diagram while you're doing this also. I had to bounce back and forth a lot.
