Hi guys,
I’m in Australia so I have got my 370gt imported from Japan recently. I have done some research about the paddle shifter installation and figured out it no one has figured out if they can actually wire the paddle shifter if there is not pre-wired and taped down the steering wheel, or they did but didn’t post on the internet.
So can you actually wire it yourself? If so how hard can it be?
thank you.
I have opened up the interior but did not found the wire
Assuming your car has "Manual Mode" on the floor shifter, adding paddle shifters to a car that is not pre-wired can be done but you will have to run 3 wires from the steering column to the AC Amplifier that is mounted in the center part of your dashboard. If memory serves, there are 2 signal wires and 1 ground (earth) wire. This also assumes that you are able to source a set of paddle shifters preferably with the wire connectors (pigtails) attached (just makes it easier to splice).
Tomorrow I will check the FSM for you and advise accordingly. However, being that your car is, technically, JDM, the wiring might be different than our USDM manuals. Will see what I can find out for you.

Welcome to the site!
Thank you, and yes it has a manual mode, I will start taking the interior off
As promised...
The following schematic will show how the wiring for the paddle shifters is sorted. You will have to run 2 wires from the paddles to the unified meter AC amplifier connector #66 and source a ground wire from the steering column:
The unified meter AC amplifier is a small, white, rectangular box mounted to your CD headunit. There are two connectors. M66 is the wider of the two with 40 terminals (2 rows of 20). The hardest part will be sourcing the terminals (if you are lucky they will already be there):
This should get you started. DISCLAIMER: the above schematics are from the USDM FSM for the G37. I checked all of the FSM'S I HAVE: 2008, 2010, and 2014 and the pinouts for the paddles are the same across those three (3) model years.
HOWEVER, being your car is JDM-spec, there is a small possibility these values may be different. I do not have any JDM manuals. Therefore, proceed at your own risk!

It is not as complex as it seems. I am sure you will get everything sorted.
I would double check your steering column harness just to make sure the paddle shifter connector is not there. Unused connectors are very well taped up and hidden.

I have the same issue, my 09 g37 coupe journey has no pre-wire. will please make a video or provide picture of how you wired yours.

I'm having trouble following this. I've put the wires in the right spot, and found a ground, but still won't work😕
My car did not come pre-wired. If you look on google and search for what you're looking for with a good choice of words then you will come across a certain thread or two (there are many actually) that has some pointers.

could you possibly tell me what choice of words to use? Ive been searching for days with no concrete way of doing this. Ive even tried tapping into my manual shift wires.
What part do you not understand? Everything in this thread shows you what needs to be done. The paddles Nissan uses (whether you have the column or wheel mounted type like I have) are only SPNO (Singe Pole, Normally Open) momentary switches.
Each paddle has a 2-wire connector: one (1) wire goes to A GOOD ground while the other wire goes to the appropriate slot on the AC Amp. When you pull the paddle, the switch closes and this completed circuit sends a GROUND signal to the amp which then changes the gear. None of this is rocket science.

Tapping into the "Manual Mode" circuits (slots 5 & 25 at the amp) likely will not work in this case as there is no GROUND source to complete the initial circuit. Even if the shifter was permanently in "Manual Mode" the paddles still need a VERIFIED ground.
Others have added paddles using the above method with no issues. The hardest part is sourcing the wires with the female terminals that can inserted into the connectors.

Again, what do you not understand?
What is a verified ground? Ive just been grounding to the body.
Can someone install wire harness for me?
