Slimg60 0 Posted July 17, 2007 Just got a new instrument cluster for my car (cheers blue_joe) that have DDI dials already fitted. Just wondering where abouts the red and black wires are connected to? Cheers Quote Share this post Link to post Share on other sites
KADVR6 0 Posted July 17, 2007 you normally connect them to the headlight switch, that way you get the power/dimming facility. Quote Share this post Link to post Share on other sites
Slimg60 0 Posted July 17, 2007 Cheers, off to wire them in now! Quote Share this post Link to post Share on other sites
Andi 2,147,483,647 Posted July 18, 2007 Red = live, black = earth. If you wire the red to the variable voltage coming from the dimmer, it'll still dim then. The black can go to any earth point. Quote Share this post Link to post Share on other sites
