CIS picture of backside on test bench
 

Can someone direct me to a picture i stumbled upon that shows the entire CIS system from the back side sitting on a work bench i think?

Hope this helps. These are all lambda systems.

nice pics
 

I am looking for the brake vacuum bost hose , should be 3/4" od ive been told.

also, what are those bright green plastic rectangles, just curious?

Nice pics ty

Isn't that on the firewall, by the cruise control servo?

brake vacuum hose
 

Ive been told its along the firewall and then down on the left side, but i cant see where it connects to a vacuum source

Frequency valve. In the very top pic, you can see the bottom end plugged in. You can't see the top end as the rubber bellows is moved out of place.

Plug wire goes from one turquoise plug to the other.

no, the one on the left on the air flow meter (AFM), goes to the switch that cuts off the fuel pump when the key is on and the engine is not running. the other one is the cold start valve

The one on the top is for the air sensor plate switch and the other is for the cold start valve. BTW, the brake vaccum source is located at the air box driverside and it goes down to the bottom side of the firewall. Search for John Walker's post about vacuum leak and has a picture of the brake vacuum hose going to the firewall. HTH.

Vacuum line to brake booster......
 

The vacuum hose is connected to the driverside of the airbox and next to intake manifold #3. The other end is connected a steel tube by the firewall shown in John Walker's post (vacuum leak). See below:

boy911sc thank you
 

How do you get such good pics, thats exactly what i needed.

I replace the warm up regulator vacuum hose, some improvement, but still backfires.

thursday the red and blue distributor vacuum get replaced and im going to recheck the fuel pressure.

after that im going to trace the brake boost vacuum line.

Its getting cold in northern ohio, running out of time before it all gets packed away in the barn.

See the link in my sig if anyone needs a bunch of higher resolution CIS pics.

MCA, thanks for the download of CIS pics, very nice.
