Installing a Whelen UHF2150A flasher into a 2005 Chevy Silverado. Are the headlights pos or neg and what color is the trigger wire at the bulbs?


Thanks

As EVS stated, POS switched system.


For the UHF2150A you ned the Light Green/Black stripe on the right side, and the Light Green/White stripe on the left side.


Just finished doing several suburbans so it is fresh in my head for now. Holler if you have any questions.
