Here's a vacuum line that runs across the top of the firewall, it is connected on the driver side, but where does it hook up here at the passenger end?

 

Don't know. It doesn't look factory. What does it connect to on the driver side?

 

it runs across the top of the firewall...



and here's what it connect to on the driver side... its a '94 pickup BTW

 

I dont think I have that on my truck. I'll take a look next time.

 

On my 3vze this line goes to a black three way tee in a line marked *#, that connects to a black plastic attachment with three vac ports in the manifold. Your truck appears to be the four cylinder, and there appears to be a black plastic port just below your fingers (below and to the right at about 45 degrees) in the first photograph. Does it have an unconnected port that is out of sight?

hope this helps

 

not really. This line is definitely factory.

There's gotta be someone on here with a 94 22RE...

 

yeah that diagram has me even more now, lol

 

I just checked mine and all I have going across the firewall are what appear to be 3 brake lines. I don't have that device that's on the right side of the brake booster, thus I won't have that vacuum line.

Mine's a California emissions, does that make a difference?

 

it looks for the cruise control. it should go somewhere on the intake manifold.
