NEED STS Wiring info quick!!! Buddies at a shop are hooking an STS up and the instr. book says:
"the single brown wire goes to the PCV Switch"
and then
"The other two wires go to the 1psi switch"
Problem is, in the wiriing harness there is a brown wire, with a red wire, no other single brown etc. WTF?

If this is like the GTO kit, there is a red (?) and a brown wire. The red wire is hot, the brown wire is switched. So, you put them on the 2 terminals on the pressure switch, then jump from the brown on the pressure switch to the terminal on the pvc solenoid.
The idea is: you are supplying 12v to one side of the Hobbs pressure switch; when it hits the preset pressure, the connection closes, and the other side is now hot (brown). This does two things: 1) by jumping to the pvc solenoid, you have now closed the pvc from the throttle body (or wherever, in the pressurized intake tract) and thus don't pressurize the valvetrain, lifter gallery, etc. 2) the switch kicks a relay in the harness. Normally there is a big power resister (has a heat sink on it) that is wired in-line with the oil pump to keep flow low; the resister is stealing current. BUT, when you are under boost, the brown lead kicks a relay, and the oil pump gets full current, so it flows more.

Glad to be of assistance. I've had a LOT to look at with this process: http://www.ls1gto.com/forums/showthread.php?t=36150
I still have the little baby .25 bar spring in, only ONE MORE WEEK until I can get it tuned. Put in the .6 bar spring and 0-5 psi adjustable controller; bigger injectors; activate the fuel pump voltage unit; activate the methanol controller; and burn up the Toyo T-1's! Yee haw!!!

Hmmm, I didnt ask what spring he has in? I threw in a preliminary tune already, so tomorrow morning should be able to get it off the lift and out on the road. He also ordered 60# injectors and Walbro 255l pump with hotwire kit (and a hotwire kit for me too!).
Im the guy with the STS tubo CAT3 is helping out. Thanks for the info. I was having a hell of a time trying to figure out what to do. I was thinking the same thing you suggested. I was just scared to try it without more input and we all know STS is a Monday-Friday buisness so they couldnt help me. Thanks again!

I have the .25 bar spring on purpose. I knew I was going to be driving the car a long way to get it tuned, so I have that spring in the wastegate. I also have the .6 bar spring. You likely have the .6 bar spring. That should yield 7+psi after the intercooler. Mine should be 7-12psi adjustable...1 week to go!
