im doing a 3800 sc engine swap I bought a boost gauge ,,,where do I hook up the hose for the gauge sensor? on the small outlet on supercharger where one goes to some contraption bty what is it and one is capped off and im guessing the bigger one goes to brake booster? any help is appreciated thanks
On my car's sunbird tach/boost gauge, a wire runs to the MAP sensor. The MAP sensor plugs into a small nipple right underneath the supercharger snout. So if you have to connect to a nipple, that one is probably the one to use.
