Can someone answer this question
What I'm confused about is an inconsistancy in the wiring diagrams. If you have a look here at the RB25 ECU pinout you see NO mention of anything to do with the throttle valve switch.

But here in the trouble fault section It tells you how to diag it and mentions pins that either dont exist or are used for something else.

Is the throttle valve switch the grey plug on the s2 harness that gets cut and discarded? with RB25 that idles properly, is this throttle valve switch still needed with the rb25 ecu? Is this only needed for an auto ECU or does the 5spd ecu still need that sensor input?
Apparently the ecu should be putting out 8-10V on that circuit but my ecu only puts out a 5V reference. This input should be necessary for idle control in conjunction with the TPS should it not?
