Just do 1 step at a time

Basic directions for connecting 2STEP/CLUTCH wire:

1) Locate green power connector, open bottom flap, and remove #8 orange wire. Place 2STEP relay red wire in its place. Connect #8 orange wire you removed to the 2STEP relay blue/white wire using preinstalled connector.
2) Put green power connector back in its location with relay hanging below or next to it.
3) Connect 2STEP black, which will have a wire nut connecting to an extension wire, in to the USB cable position #7.
4) For the NLS to work you must also install a clutch wire. Connect this to USB cable position #8.
5) Connect the male/female end of the clutch wire in to the gray DME connector position #18 as read from the female end. Either by removing the PNP connector and extracting that jumper wire, or simply removing the wire, sticking the female end in, connecting the OEM female wire in the new male pin, and folding a piece of tape in half over it. The wire needs to read the clutch signal.
6) To enable NLS you must set FutureUseE (previously bogfix) set to 0. NLS will cut engine power when pressing the clutch while gas is fully pressed and restore it when you let the clutch back out again. Practice doing full throttle runs at lower RPM to get the hang of it. When you press the clutch in while the gas is 100% down the RPM should drop like a rock. If they don't, you've botched the install.
7) Note if the car cranks without starting after installing the relay something is likely wired wrong. If you are unable to sort it out just email in install photos for support.

im pretty much lost between step 3 n 6
5) Connect the male/female end of the clutch wire in to the gray DME connector position #18 as read from the female end.

6) To enable NLS you must set FutureUseE (previously bogfix) set to 0.


which one is the clutch signal wire? is it located by the pedal? if so im sure there is at least two wires there for that sensor, which one do i tap???

I came across this post after google-ing for the answer as well. There's a write-up here: http://www.e90post.com/forums/showthread.php?t=874651

Note, follow the diagram, not the instructions. At the time of writing this, the wires on the USB cable were backwards.
