i put a b18a1 into my civic ef and i cant figure out how to hook up the map sensor from the b18a1. the b18a1 has a different plug and more vaccum lines on it then the stock ef plug i was going to use the stock ef ma sensor but the b18 manifold has more vaccume lines , can some one please help me thanks.

 

Just run the 88-91 civic vaccum terminal and run a vaccum hose from throttle body nipple (its on top next to the bigger vaccum hose tha runs to the charcoal canister) to the map sensor. The only real vaccum lines you need are the map, fuel pressure, and brake booster. All the others can be removed or capped off. Depending ont your opinion of epa rules and regulations.

 

thank you i will be trying that
