I own a 97 240sx. Im looking to buy a s14 sr20 converted plug and play swap thats running into a 95 240sx OBD1. only problem is even though it is an s14 chasis and the plugs are the same, from research im seeing that the s14 dash plug (f4) have minor but some differences in the pinout between zenki and kouki. I have pieced together a s14 dash plug chart for the sr20. but what I need is the USDM F4 plug charts for a 95 and also one for a 97 so I can cross reference the differences between the 2. In short its like puttin a ka24de with harness from a 95 into a 97. anybody understand what Im sayin lol

Yep everything works. My vvt also works. My engine was from a kouki s14 not a zenkie, so pin 23 that is supposed to be grounded to pin 10 was for the fuel pump on my car. If you are getting a zenkie engine you should be good with following the above layout line for line. Good luck.

^ also I would suggest getting familiar with nissan wire colors, if you are not already. Common sense can also be your friend. The sr is a fun engine so the swap is worth it.

so your sayin [Fuel Pump 22 B/Y S11 B/P] is for zenki models, but for our 97s [Fuel Pump 22 B/Y] has to be moved to pin 23 in order for fuel pump to cut on. and im guessin you take the old [f3] pin 23 and ground it with pin 10? correct

I had a pin-out saying to ground pin 23, which was a bad idea. I got lucky. I would suggest checking left over wires in the repin for 12v.
