GMC Sierra Vs. Sho-ME Flasher

[OCRS11-11]

I could use a little help, and any will be appreciated. I have a 2001 GMC Sierra, and a Negative Switching Sho-Me Headlight flasher. I have tried installing it, and I get no effect out of it, maybe I'm doing it wrong, I dont know. The truck has what appears to be purple, and an orange wire connected to the bright lights, maybe someone can help.

Two things:

1.) RTFM

2.) GM uses a green wire for the high beams

Don't touch anything until you either know what you are doing or you find someone who does.
