I bought a Lamco boost gauge off of someone but it appears he just ripped it out of his car after it was totalled. The previous owner said he got it "professionally" installed.
My problem lies with wiring. The professionals deemed it unnecessary to use the included harness and went on to wire it themselves. Now I have a positive wire and a ground wire to run the boost gauge lighting which is fine, I just don't know where I can run it to so that the light turns on when I turn on my headlight or parking light.
