go to www.my427sc.com and look up the diagram in his lights section on the build page. I used that with my tri-state turn signal and it was pretty spot on.

I used a multi-meter to figure out which color wires on the turn signal were the right ones to connect to the dash harness.

 

There is no link to the turn signal section on the above web page

 

From the home page, click "Build!", then scroll down and pick "Lights and Accesory Wiring", then scroll down through the pictures to find a schematic.
