Q: Supplemental LED turn signal

asked by on February 26, 2017

1994 p32032 Chevy chassis motor home. Turn signals have three wires, white in center, Brown and black on either side. I'm trying to wire in a supplemental LED flasher, and I need to know which wire is positive, and which is negative. I don't want the light on when running lights are, just flash with the turn signal.
