What do these m20 parts do?

[pizzaman]

I didnt want to post in the m20 section because I feel like the general discussion gets alot more views and I need these answered pretty quickly.

1st. hole on the right side of the throttle body. I've seen e30 pics where it connects to the brake booster, but this is in a 2002. Do I need it?


2nd. The two hoses on the backside of the fpr. What goes into these?


3rd. Where the f*ck does this go?


And finally, where does this plug plug into? Further down the wiring, it splits off and one parts plugs into under the tb

Thanks!

I am moving this to the M20 section cause that is where it belongs. But i will put a redirect so the people who wont leave the general disscusion area can see it and look at this thread.


I'm not just going to pick on you (cause i know why you put it in GD), but it's getting very tiring to have to move everything out of general disscusion cause people are to lazy to scroll down and look at the rest of the forum.



The 1st picture is for the coolant to go to the TB. You can hook it up if you want hot coolant going to your TB. But most people bypass it.

Those 2 lines on the FPR are fuel lines. Bottom line is fuel feed and top is fuel return. That pipe is a breather line from the rocker cover to the LH side of the throttle body. And i dunno about the 2002 brake booster set up.

The hose is your heater hose, that goes into the coolant reservoir and into the outlet/flange on the cylinder head. It runs underneath the intake.

brake booster vacuum

top line is the fuel line feed , bottem is a return line.

3rd. Where the f*ck does this go?


those two hoses go under the intake to the heater core.

ones the plug for the TPS , and the other should be for the AFM

Thanks!

Thanks a ton for the help guys. What if I do not have a heater core? Can the outlets just be blocked off? Do I even need that hose?

you just need to re route the hose back to the Thermostat , you just wont have heat in your car lolz. Im thinking I should have done this when i had time since my heater dosnt work very well. it would clean up the look under the intake. GL

Looks like the plug n play wire is the ICV sensor. It plugs into the idle control valve
