owners with Autometer Phantom II ?'s

[lethal injection]

I just hooked up my bosst, pryo, and fuel pressure guage. Tied them to the dimmer switch and the pyro and fuel dim as they should but boost stays at full brightness. There all tied to the same wire. Any ideas?

The Phantom II's have LED light bulbs. Which usually want work with your factory dimmer. Autometer makes a dimmer for these gauges. The number is AM-9114.
