ok the wiring is making more sense to me now, after searching for countless hours for diagrams and pinouts etc, i started to notice something, Every pinout for the f4 plug was wrong, but only wrong in the aspect of the Pin #'s they were flipped, i'll post pics to show you.
this is a very common pinout found all over the net for an s14 zenki sr20det
but its wrong, you see how pin 9 shows its purple and its a wiper?, well that should be pin 1, its like they have the color and functions viewed from the wire side but the pins are viewed from the plug side, this will cause alot of confusion lol.
and i know that they are backwards, spent 4 hours last night making sure in the FSM for a 96 silvia zenki sr20det, when every pin and function matched up but the pins were perfectly backwards.
here is the correct pinout. i just edited that same image in paint
and a more visual version (which helps a little more when re-pinning), this is also a diagram i editied in paint
almost all the f4 diagrams ive found online have the same mistake.....except 1 this guy has a blog about his s14sr into s14 swap:
http://gskoff.blogspot.com/2010/04/s14- ... frame.html
and on that page there is a link to "240sx Electrical System" that is his diagram of the OEM 95 240sx f3 plug pinout, the Modified to work version (repined) of the sr's f4 plug, and finally the OEM zenki sr20 f4 plug pinout.
after i went through the FSM and wrote down what i found (triple checked this stuff) i compared it to my findins on the zenki s14 f4 pinout, and they were exactly the same, wirecolor, pin # and function.
and his 95 240sx oem pinout was ALMOST the same as my 97 240sx pinout,( there were a few color changes in the wires and a couple wires added in obd2, but it all matched up. so that being said i basically have the wiring figured out for the exception of the ac working 100% and the rear defog (pretty sure i'll just be adding in a wire from the sr ecu to the f4 plug) the ecu has a pinout for it but the wire isnt there (only came on auto's IIRC). so thats where im at right now lol
