I swapped a ls into my civic and i sent the harness to Rywire and when i got it back everything hooks up fine, and it starts fine to, but i have two sensors that don't arent hooked up and i dont know what the deal is with the vacuum lines, if i have them misplaced or what? It runs good, but i just wanna make sure that i have them right. Also i looked at this diagram below, but it doesn't have all the sensors that i have on mine, So if someone can post a pic of their vacum hoses that'd be great.. Thanx

 

The sensor you have circled is your MAP sensor, you hvae to plug this in. Your current map is the 3 wire sensor on your firewall, unplug it and plug it into the throttle body mounted map. You old map is now unused.

 

Dang, Thanks! I've been trying to figure that out for a few days, since I just got an intake manifold from a B16A3 for my 92 integ.

 

can any one post a diagrame of a b18b vacuum line set up
