I found the vacuum line that runs across the firewall disconnected. It comes from the cruise control and runs across to the right side of the engine compartment. I can't find where it connects to the vacuum source. I haven't found a vacuum diagram online that shows the cruise control vacuum line.
Anyone know where it connects?
Thanks.

I looked through my '93 and '95 manuals, they talk about it but do not show the vacuum diagram at all. I even looked at my supra (same actuator as the 4runner) but it comes off the intake plenum, the 22re does not have the same port.

Best bet here is to have someone post up a pic of the vacuum line coming from the actuator.

I can post a pic of my 93 later today if no one else does. Mine is the 3.0

Wazukie that would be great. I forgot to state I had a 3.0
Thanks.

Umm, as far as I can tell, the 3VZE is mechanical, not vacuum operated. At least that's what the manual says.

From the manual:

Motor Type (V6 3VZ-E Engine) Actuator consists of a motor, safety magnet clutch, control arm and position sensor. When actuator receives a signal from CC ECU,it engages safety magnetic clutch and activates motor. Motor causes control arm to move, opening or closing engine throttle valve. When motor rotates forward, control arm also rotates via safety magnetic clutch, gears and drive shaft. Control arm pulls a cable connected to engine throttle valve and opens the valve accordingly. When motor rotates in a reverse direction, control arm also rotates in a reverse direction and engine throttle valve closes.

Here's a link to the '95 manual, shows both 22re and 3vze styles:

EDIT: Checked the '93 manual, same images and info as the '95.

Interesting. Mine has a vacuum servo mounted on the driver side fender.

So, the first picture shows the vacuum line connected on the drivers side near the cruise actuator. The second pic shows where it is hooked up after it crosses over on the firewall. Hope it helps.

Thanks Wazukie.
Just what I was looking for.

i see your headers-- was it a easy install?

Real easy after I installed 1" body lift to clear the firewall.

As little as it is, here's my thread on the rebuild

93 3.slo rebuild

Do the headers make make a difference in your butt dyno?

I have not been able to have the full experience as of yet. I am only about 300 miles into the break in of the new motor.

Does anyone know how the cruise control brain on a 1995 5-speed gets information about vehicle speed? Is it from the speedometer in the dash? Or does it try to hold constant engine RPM? Or something else? I have searched my repair manual and can't find details, only generalities ("speed sensor").

My cruise control is jumpy, and so is my speedometer (the cable is bad and binds/releases, causing the needle to jump a lot). This seems to indicate the CC speed data comes from the speedometer needle in the dash, and replacing the cable would fix my cruise control also.
