Bit of an issue
Just picked up a m/t to attempt this swap. Once I got home I noticed the harness was cut. How much of an issue will this present, not sure if I absolutely need anything wired up?? Thanks
Are there specific wires I need to worry about in there?

It doesn't matter as the harness is the one from your engine if you use MT engine harness... if you use AT engine harness, it will still works but you will have wires not connected and check engine.

Sorry to bring up an old thread. I just got my hands on a 350z M/T ECM. I'm planning on getting a M/T engine harness as well. But what I was wondering is if i plug in the M/T ECM and change the engine harness will the car start. I noticed that the clutch pedal has a Clutch Pedal Position (Start) Switch. My questions are as follow : 1) Will the car start even if i dont have that switch on the pedal? 2)Will I have to change the interior harness?

Sorry, I just spotted this and have never done such a change, but will attempt to provide some answers. 1) The small clutch pedal position switch is a safety feature and no, the Z will not start unless the switch is "on the pedal". 2) You didn't specify whether your Z is an auto or a m/t, but if it's the former, my guess is, yes you'll need a different interior harness.

car speed
my g35 is converted to manual and has been for the last year, the car runs fine, but the only issue is that it doesnt pull when i floor it, it just gradually speeds up.
can this be solved by swapping out the ECU to the 6speed ECU ?
I have an 07 DE non-revup.

I know this may not answer your question but are you using the auto cluster or m/t cluster

Idk if i may be right. But perhaps it may be the ECM. Not so sure. If youre using the manual harness and and auto ecm its probably not getting the signal that youre flooring it. You can buy a manual ecm for cheap on ebay. Thats where i got mine for 80 bucks

Thats the same as the ECU right, I plugged it in and the car wouldn’t turn on and it would just crank, so swapped the AT ecu back in.
Tha harness is manual , the auto one wouldn’t let the car turn on first try because the neautral position sensor not being wired up and I didn’t wanna do any wiring in the main computer.
I went to a shop and they told me the fob and the computer had to match the car because then the key wouldn’t program and the computer wouldn’t match the other computers in the car.
Thanks for response.
my car is 07 with DE mon rev-up
so I had to purchase an 04 ecu as the 07 had rev-up

So all you have to do now is just have your key fob programmed to your car. If you dont mind can you message me on Instagram i would like to ask you some questions. My Instagram is @darthnismo

Other than that you're good. The starter may be on the other side but just switch it over. Assuming it isn't a AWD automatic, if it is move on. The upper oil pan is different to accommodate the half shafts and front differential.
