Wiring Harness And Aftermarket Ecu's

I just spent a full day driving around different wreckers here in Auckland and went through the "automotive dismantlers" section of the yelow pages from page to page. I still cannot find a single person that has a Wiring harness and ECU for an RB25DET R34 NEO Engine (its going into my S14 silvia). Everytime i ask a wrecker if they have any NEO 25t parts i pretty much get laughed at. I might aswell be looking for bloody Dodge Viper parts.

The NEO motor i bought came with a cut wiring harness (lazy bastards), no ecu and afm. The lack of parts has caused me to look at the aftermarket. Im confused about aftermarket ECU's and their wiring harness. LINK is obviously popular here in NZ and i was wondering about their "wire in units". Now, the website claims that it comes with its own wiring harness. Does this mean i can use the LINK's (or any other aftermarket wire in ECU) harness completely instead of finding a nissan wiring loom or does the "LINK wiring harness" simply splice into the factory harness? The harness on my motor is all their except its cut where the loom routes into the firewall and plug into the computer..

Ive been told that a NEO wiring loom will need to be specially ordered and cost around $400-500. ECU is just as rare and will also cost easily over $200. AFM will not be cheap either. The LINK will do away with the afm, and if i have the right idea about the wiring harness, then the LINK will solve my problems in one hit.

So basically, my question is, does the LINK harness act as a complete engine harness (or can it be easily spliced into my current cut harness)?

As usuall, any help is greatly appreciated! ;)

    • Meh. I "see" a typo above, that should have been "sell".
    • The clutch pedal has a procedure for adjustment. This can only be done after you are 100% sure the system is absolutely free of air bubbles. You must bleed the clutch master cylinder first, then the "separation pipe" which is the clutch damper line, then the operating cylinder as detailed in the service manual. Also, you must fully depress the clutch pedal between shifts. Just because you can't feel it grabbing does not mean the input shaft is truly decoupled from the crank. At high RPM clutch plates are vibrating and moving around, you need to give it the best possible chance of success. On the BCNR33 Nissan revises these adjustment procedures slightly but not by much: I would be careful with trying to play games with these adjustments. As for the Nismo operating cylinder they say a lot of things. In practice the twin plate clutch needs less movement on the clutch fork to disengage because the whole stackup of the flywheel + friction plates + pressure plate is much taller. Personally if you find that the clutch still disengages too high at the top of the travel I would try the Nismo operating cylinder. Make sure to follow the air bleed procedures. 
    • Thank you for the links. I’m going to go with the 6pin plug you used. next step is rust treating re painting dash support bar and steering column then the 6pin cradle plug when it arrives in the mail.
    • I don't how much the car makes a difference or whether it is just a question of gearbox and clutch. On mine it's fine. Pull type Nismo coppermix twin (standard, not competition) on the 5 speed in my Stagea. OEM slave cylinder. Bite point is a few cm off the very bottom of the pedal. Clutch pedal all the way down to put in gear, and when heading off at the lights, there's a tiny bit of nothing and then it starts biting. And fully engaged before the pedal is all the way released. There's a bit of play at the top where the pedal does nothing anymore. Are you in Australia @ck_chino? If you are set on using a Nismo slave cylinder I have one new-in-box at home. Ordered it together with the clutch but didn't get it fitted. We can work something out if you want it
    • I am using a pull nismo coppermix twin in an r34 getrag box, had both the standard slave and  then the nismo one. Adjusted pedal to get bite point how I wanted , it is on the higher side, but would fully disengage past half way down.  I also read that the nismo slave won't work but I had no issues with the stroke, might become one later as clutch wears but 2+ years of happy motoring so far.  Take the above as one input only, specially as my setup is a bit unique in that I am using an S15 clutch master , cefiro clutch pedal, custom braided clutch line. Lots of variables at play.
