how do you tell where all the hoses gone when u finesh wireing for mpfi like the hoses on the throttle body , intake manifold which 1 goes where ?

 

also on the driver side of the engine compartment there ar 2 hoses that i dont know where they go 1 hase fuel the other i think just a vacum an diagrams ava.?

 

what intake manifold? what throttle body? what car?

 

a6 mani, 91 civic, stock throttle body i need a hose diagram for all the hoses for mpfi swap and i need to know where the hose from i think its the brake master cylender hose its right on where the brake fluid is where dose that hose go and i need a diagram for the coolent hose ive pluged all the vacume hoses up so far just want to double check

 

Honestly, all this info can be found in the FAQ----Do a little reading...

 

here is the vacuum line diagram for 89-91 D16A6 - notice that on the back of the intake manifold, the 89-91 had a Fast Idle Control Valve - since you did the DPFI to MPFI swap, you have no wiring to plug into the FICV - just cap off the vacuum ports for the FICV and leave it not connected - it only works for very cold temperatures (below -10c or 14F) and just boosts the idle slightly - the FICV is circled in the other picture - the brake booster line connects to the L fitting just to left of the FICV

Thats even better, for the kids who dont know that its the same thing for all OBD0 honda engines.....LOL minus wherever the FITV is on particular motors.

</TD></TR></TABLE>yeah, except 88 Si is a little different - it didn't have a FICV, but used a dashpot solenoid on the firewall to boost the idle when cold - like this:
