the colored plugs on the drivers side of the motor next to the oil filler tube... what order front to back do I put them in? had someone helping me the other day, and they were unplugged without reference to the order of the plugs... GREAT.

any help would be appreciated. I did search, but was unable to find that magical all answering post after looking through several pages, and burning an Hour...

thanks.

If they're in decent shape, they'll still have colored dots on the solenoid body that will match the plug. Otherwise, take a look in the manual at the vacuum diagram. Page 4B-5 of the S4 manual if you have an S4. Otherwise, you can find color coded vac diagrams with a search of this section.

Solenoid colors are:
FPR: orange
EGR: yellow
Relief: blue
Switching: gray
Twin-scroll: green?

A quick search turned up this one for an S4 NA: https://www.rx7club.com/showthread.p...vacuum+diagram. For an S4 TII, everything would be the same except you'd have a twin-scroll solenoid too.

Earlier this summer I removed the rats nest from my S4 TII. RotaryRocket88 helped me out and the whole project really simplified the top of my engine and it runs much better now. Here's the link for a little more info.

If you're cleaning things up, remove all the solenoid valves except for the Green Twin Scroll valve. You'll want to keep that, my car had the Twin Scroll removed when I bought it. I didn't think much of it until I added the system back in. It makes a difference regarding torque with the stock turbo.
