Heres my problem... I have just installed my triple gauge set (trans, boost, pyro) on my 08 f-350, they are the autometer phantoms. So i have them wired up and they work great except the lighting. The lights work but they appear to loose power or something as they go up the pillar, for example the bottom gauge is bright, and they gradually get dimmer. I have all three light power wires wired together and then to the purple with gray stripe on the headlight switch as directed on the autometer website.
So why are the lights dimmer as they move up the pillar?
Any help would be great......
