sr wiring harness

[pavmentscreaming]

I just bought a wiring harness(non refundable) serial Number 24011 52f22; the problem is most of the plugs do not plug in, and the ecu pinout is a bit sceptical. I have a E5 ecm and a 97 blacktop non vvt. btw There is'nt a plug for the ignitor chip, mabyee C-O-P harness? Im not sure but cant seem to pull up the serial number, any help?

NO one? Okay the ecu plug fits the e5 type computer but doesn't have the plugs for the ignitor, the Cam angle sensor is a 6 wire plug and the only plugs that plug up are the injectors, idle air, throttle ps, and the computer. I have been researching and couldn't come up with anything, I was thinking I could be a sr20de harness because of the ignitor bypass. Ignition signal one white wire runs to cas plug and ignition signal 2 runs to a different plug. any help i can post pictures or what ever you need.

no name by the serial number?

[pavmentscreaming]

yeah sry, everything is faded; the only name i see that might be the one is JECS japan.

Anyone know what these 4 plugs are, none plug into the engine.

'97 blacktop SR uses the J4 harness/ECU.

I have a 96 blacktop, Im just not sure of the harness the ecu pinout isnt a j4, wc, e5,j2 or any of those, all of the ignition signal wires run to different places, no ignitor chip plug, the throttle position wiring runs to three other plugs that do not plug into the engine, Im thinking this is a sr20de, non turbo harness but cannont find the part number. I have called nissan directly and they told me to give them till monday. Can anyone verify these plugs.

I posted the 97 in the above, later did i figure out its 96. I had the original harness but all the wires were pulling out from the ecu connector and someone prior to me hacked it a little more than i could put up with.

[pavmentscreaming]

Okay heres what pin 9 does from the ecu plug; it runs all the way up through the harness to a resistor of 2 ohms and back down and through the injector side to a 2 prong plug. The other wire from the plug runs into pinout number 36. The j4 harness is empty in pin nine and a E5 pin 9 is Ignitor 3 wire. None of these wires match any diagram or pinout ive looked at or make any sense.

[KiLLeR2001]

You either need to fix the harness you have with the correct pin out, or you need to buy a new E5/E6/62/63 harness to save yourself the headache.

[pavmentscreaming]

Im pinning it out right now, so how about this; instead of trying to figure out what i have can you tell me what pins i need to run the engine efficently and correctly and what i do not need? Well besides the obvious
