on each mirror it comes with 3 wires : brown , red , black

my question is how do i install these mirrors ?? because the stock ones have that white plastic thingy on the mirror where the plug can goes in , where this new mirrors only have 3 wires ???

thanks guys

 

heres a guess, t tap the wires into the stock harness ?? not really an electrical guy just trying to help

 

lemme guess

red = +ve
black = -ve
brown = horsepower adder (at least 10-15 whp over similar mirrors)

 

Just a guess....

Black - ground
Red - positive
Brown -signal wire

Try taping into the wiring harness on the car just below the plug. Or, if you can remove the plug form the factory mirror and reuse it.
