Definitive R34 Gtt Wiring Pinouts

[Mitchee]

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.

I know this is a bit of an older topic, but this has been an excellent resource for me Mitch. If you are taking donations let me know your Paypal address. I feel like I owe you a bit for taking the time to do this. Laugh.

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.
