vacuum diagram
 

another thing that i have to figure out for this weekend. i've searched online and still couldn't find it ???. i've already done the mpfi swap on the crx dx but the map sensor on the b18b is on the intake manifold. how do i tackle this??...can someone would be kind enough to just post up a diagram on where things go to make this man happy. thanks in advance.

download the '94 integra service manual - page 200 of the pdf, 11-8 of the manual.
it looks pretty much the same as the D16A6 vac connections - there's a line from the back of the IM to the bottom port of purge solonoid on the firewall, then the side port goes to the top (control) port on the charcoal canister. the connection just below the control port should have a fuel-proof line going to the nipple on the throttle body next to the MAP sensor. finally, there's the PCV line and FPR line - pretty self-explanitory.
the MAP sensor operates just as the stock CRX sensor would... there's just no vac line between the sensor and throttle body.

you just plug it in ;) it's not on the fire wall like the original one, it's right on top of a vacuum source which eliminates the need for a vacuum line.
