Anyone have pictures or drawings of how to hook a Map sensor on a JDM b16a? because I searched and people say "tie it to the firewall and put a vacuum line on it" what does that mean where does the vacuum line come from? Please help! it's a b16a into a 94' del sol si. Wiring harness from the old motor map sensor also.

 

it comes from a TB. Just look you will see a thing you hook up the line to.

 

Are you talking about a 3 bar map sensor? If so, very easy. Follow the directions and you cant go wrong.
