Attached is an Excel document which I painstakingly put together by hand, as I found some R34 GTT diagrams out on the internet either completely unavailable (bodyloom/m53/f3 plug) or unreliable (ecu pinouts)

Ive sacrificed an entire engine loom to get this mapped out correctly and Ive taken the liberty to add in all wire colours.

The first worksheet in the document is of what I call the 'body loom' plug or 'M53' or 'F3' plug if you are familiar with other Nissan looms. This takes all input/output from the ecu to non-engine related things. In the case of the R34 this is things like the auto trans control, traction control, dashboard outputs and inputs and power/switch feeds and triggers. I required a pinout of this plug as when going a full wire-in aftermarket ECU, many of your connections will be made at this plug. Nowhere on the internet could I find a correct pinout of one of these for an R34 GTT.

The second worksheet in the document is a standard ER34 (auto) ECU pinout, with all pins labelled as to their function and also the wire colour.

Enjoy, I hope this helps anyone who needs it. :)

Just wanted to say a big thankyou for putting this together, really appreciate it :)

Reviving an old thread because I pulled the trigger on a wiring specialties harness for the engine side then went Haltech 2500 and a Haltech PD16. The idea being that the PD16 will effectively eliminate ALL of my fuse block and excess wiring. 

I'm going to reference the excel in hopes of sorting out everything and if there's any additional information I discover I'll make and update the file. Though as others mentioned, Mitch did a great job sorting this out.

    • Don't even try to run it on the stock ECU if you're going to have the boost controller bring boost above ~10 psi. I've already told you that. If you use the Nistune ECU, you will need to CAREFULLY read the available documentation for Neo tuning, and read some threads on the Nistune forums, to discover the various things you have to do to prevent the ECU from going bananas when the boost is too high. The is a table associated with th boost sensor that must be modified to prevent it from shitting the bed. This is just one of the things that you will need to do to the tune in Nistune, because the Neo turbo ECU will be expecting to see a number of things (such as the TCS) that are not there, and you have to block the DTCs on those. It is totally not surprising to me that you are having the problems that you are, but the solutions to these problems have been known for >15 years. So just get it done.
    • Hi. Sry iam not a mechanic and iam not at the car atm so i dont know 100% but they told they measure those and even try to change those. AFM they have two. Coils are new a they have my old one too. Plugs too. ECU...we have 25 NEO stock and Nistune 25 NEO.   But i dont know if any one those could be the problem and why/if/what can cause this, Only thing they did not check is fuel...but that walbro 255 is new(like 1,5 years)... That fuel pressure gauge idk...but i let them know Any suggestions?   EDIT: how can they know if it is like you say he ECU pull power when it reaches a specific boost level that is too high? Tha car has boost controler
    • Can you clarify what you mean by boost cut, do you mean it misfires both when under load (driving) and when stationary and out of gear? Or does the ECU pull power when it reaches a specific boost level that is too high (boost control issue)? Does it occur at idle with no throttle? When you say "the ECU is OK", what ECU is it and why do you think it is OK? Have you used the NEO ECU, and if so do you have a MAP sensor attached? Same for the AFM, why do you think it is OK? Do you have any way to put a fuel pressure gauge on it (even just a mechanical one between the fuel filter and fuel rail)?
