alright i am about to wrap up my MPFI swap on my 89 civic DX, but upon closer inspection tonight i noticed that i have an extra plug over by the drivers side of the intake manifold... So i am now confused, if fact i am confused about 2 of the plugs, one of the plugs has a green/white wire and a red/white wire. The other plug has a blue and yellow wire, and i think a black wire... where do these plugs go??? also i have one vaccum line still not plugged in, it is below intake mount of the throtle body, and has an opening of about 1/4 inch. It is about the same size as the one for the red braided line, any ideas where this one goes??? One more thing to ask kinda a wierd obscure question, but does anyone know the part # for the bolt that caps off the fuel rail after the banjo and the washer???? i have a DX one, but it will not work with the SI fuel rail.
Thank you all in advance every here has been way help full.

 

after the mpfi swap you should have 3 plugs left over, i know one goes to the vacuum diaphram on the dpfi manifold, and the other two i have no idea about, as for the bolt part # i have no clue, just make a junkyard run and pull one, and for the vacuum line i will have to go down and look at mine and see

edit: ok there are three vacuum lines that come off the charcol canister, red braided goes to top of throttle body, one goes to the fire wall, and the other goes to a solinoid thing on the firewall (its black) one hose comes out of the solinoid thing and goes to the smaller port on the top of the throttle body, there is a small piece under the throttle body that looks to be about the same size as the red braided hose, thats the coolant runner hose port, there is also a matching nipple closer to the valve cover that a hose will plug in to, and that should be it.
