Need help identifying a vaccum during swap

[pattheriault]

Hose that goes behind the intake manifold just beside the vris actuator.(I have a curve neck). is this supposed to be plugged under the throttle body?

here's a close up of the vaccum

[mx3_ryder]

Yes cap it off...

[pattheriault]

I know I need to plug it! but where ? or basicaly what I need to know is under the TB theres 2 plugs on the IAC.. are both of these for a vaccum hose?

[mx3_ryder]

Sorry, dont' cap it off I was thinking it was another vacuum port below. I actually have my brake booster hooked up on that port beside the VRIS and have my pcv valve hose hooked up where your brake booster is plugged in. The 2 plugs under the TB are for the coolant lines. Did you take the old engine out?

[pattheriault]

yes I did but it was over a year ago.. that why im a bit confused

[mx3_ryder]

Take a close up picture of the front of your engine for me.

[pattheriault]

by front do you mean left side? or the timing belt side?

[mx3_ryder]

Picture of entire engine standing in front of radiator.

[pattheriault]

There's a open nipple just beside the one that is plugged to the brake booster but pointing backward instead of upward like the one for the brake booster.

This image is from a mazda millenia and you can see where the brake booster hose and pcv hose are routed.

[pattheriault]

just found my old manifold and the nipple I was asking about was plug so i think im all good. that pic make me doubt my pcv routing but ill see on start up.

[mx3_ryder]

Great, did you figure out the coolant lines for the TB?

[pattheriault]

yes every thing seem to be figured out! I still have a few ground to plug. just finished puting back my exhaust in place! Im only waiting on my new spark plug wire to come in tomorrow morning to fired it up

[pattheriault]

where do you guys placed the ground beside the starter?

[Daninski]

One ground from engine to passenger side engine mount, one clips onto the trans at the top and goes to the frame i believe. Never hurts to add more grounds. There is a big, like 3/4" wide 90deg vacuum hose that's about 2" long right below your VRIS. You would need to disconnect it to take the intake off. Make sure it's connected cuz it's big azz.
