turbo_fb Posted July 28, 2006 Share Posted July 28, 2006 Maybe the housing is ground? unless it's plastic. Quote Link to comment Share on other sites More sharing options...

BleachZee Posted August 3, 2006 Share Posted August 3, 2006 must be a digital gauge. My Autometer boost gauge has no wires except for the little light bulb for backlighting. Quote Link to comment Share on other sites More sharing options...
