Red = ?
Black = ?
Purple = ?

 

Red should be 12v (power) Black should be ground (negitve) Purple not sure. should conect to function like tac or could be to light

 

Red and Blue....crips or bloods....it just don't matter...suckahs dive for their lives when my shotgun scatters...

 

LOL.... Yeah I think DINO has it right...

 

 

Lets see...
Purple connected to 12volts dims gauge for example night time.

 

I would think:
red = 12V switched
black = ground
purple = back lighting/dimming

Or you could call Megan Racing and ask them to make sure. That's what I would do.

 

if you dont want the dimming feature just ground the purple.

 

yeah just called megan racing thanks

 

Whata n00b!
