I have searched, no luck....below is what I am looking for:

Need to tap into a dist vacuum advance line on my Pontiac with a vacuum switch...switch needs to control a 12v LED light "ON" when vacuum is applied and turn it "OFF" when vacuum is released.

I'm having issues with my emissions components on my Grandville and need to tap into vacuum line to see if I'm getting vacuum to dist or not.

A little help guys??

just curious - why not just T in a vac gauge and watch it as you drive ?

I have that now....but I really don't want a gauge hanging under the dash of the Pontiac....being a 55K mile car and all....

figured I could find a little LED bulb and hide it behind an air vent and nobody would see it
