View Full Version : how knows what this connector is for?

Below are pictures of my ST185 engine bay. The green connector I'm holding, at the moment is not plugged to anything. I have no idea what it is for. Connector is attached to the engine loom, and branches out near the intake manifold


Any idea?

that looks like one of your VSV's. On the back of your intake mani you should have an idle up vsv. Id look for that...

where is the "vsv" exactly? is that near the tvis on the intake manifold, or is it attached to the firewall?

VSV= Vacuum Switching Valve....let me check if i have pic,

It is a small switch with 2 vacuum hoses, The plug goes to the ecu. The ecu switches it on to allow more air into the manifold under certain conditions(a/c on, electrical load).

It'll look something like this, most likely on the back of your intake mani( you may have to get under the car to see it):

yep found it! , but can't plug it back
Thanks all

is it important? car runs fine. It's impossible to plug it back without moving the engine. So i'm just gonna leave it hanging

That's an interesting setup you have there. Upgraded fuel system.. but still with stock top mount IC and EGR.

haha no no no.

Story is; This was my car about a year ago>

Then I decided to take my whole car apart, and do a whole engine rebuild and modification. mods included AM(after market) ex manifold, 8mm bored fuel rail, dual feed fuel rail mod with AN fittings, FPR and more.

Eventually I got everything fitted in, but there was a problem with the intercooler piping. Because i fitted an aftermarket ex manifold; it protruded out too much that i can no longer have the intercooler piping routing as it did before. even if i tried to have the IC piping over the new ex manifold, the hood will not shut, basically not enough clearance.

so basically I've just got the stock top mount IC until i can get large enough cir clip pliers and clock the turbo so it's facing down. then my piping problems will be sloved
