Does anyone know what these two solenoids are and where they go? The red one has N370 136200-0311 12v written on it. I believe the other one is a Air Bypass Solenoid? Any help would be much appreciated.

 

blue and red one is the S5 T2 boost control solenoid, and the other is the AWS valve

 

I snapped a couple pictures of where the above mentioned solenoids are located on the engine.

 

Thanks j9fd3s for pointing me in the right direction and jpk3200 for the pics. Both are a huge help.

I am now trying to figure out 4 vacuum lines on the back of the TB. The Haynes manual looks like it's (from top to bottom) air bleed from the side of the manifold, air bleed between the oil injectors, spider for the oil metering lines, and the last one for the boost gauge? However, the 2nd nipple from the top seems the biggest which would fit the spider. What order is it?

 

Foxed.ca - Mazda RX-7 Manuals

 

Thanks again. The link shows the same diagram. I assume the manuals are right. It's just weird how the diameter of the nips are off.

 

a plastic surgeon can fix that Nipple problem..

 

^ Haha--- I need one. For some reason with your new unicorn/pony avatar and all this nipple talk, it reminds me of an old Ren and Stimpy episode. Don't ask me how they relate:

 

You are aware that clip is not from ren and stimpy, right? lol

The top 3 nipples on the back side of the UIM are fresh air and the bottom is vacuum. Stock, the bottom nipple goes to the thermowax idle control thing

 

Haha--- Dang, it's Rocko's Modern Life. You passed the test . The 1990's were so long ago.

Thanks for the info. I just hooked up the bottom to the thermowax, then matched the nips per size.

I got all the other lines finally figured out except one. The vac rack next to the BAC has 4 hard lines with one capped off. What goes to the other end of the capped line? The factory manual just shows 3 lines grouped together not 4.

 

You mean the hard vacuum lines from the rats nest? If so, I have no idea

 

I am talking about the line in the attachment highlighted in green. It is in the hard lines that attach to the back of the Intake Manifold and connect to the ACV. Where does the other end of the capped line go?

 

Where do all those vacuum lines go Joe's 7? I'm working on putting a full car back together and I dont know what is what...

 

Same here. I have just been walking off the factory vacuum diagram. Let me know if you need help. I took some pics.
