I just installed my Empeg in a 1995 Blazer it works find except for the White wire that is supposed to Dim the display isn't doing its job.

my wireing hardness has 2 wires for dimmer both switch from 0 to 12V when the lights are on I have tried both connections on the empeg and can't get a dimmer.

First with the ligjhts off I set a dimmer amount then I switched the lights on and the amount was the same it didn't give me the option to select a differet setting.

Suggestions ??

one wire is orange the other is orange with a white strip ?
