Long time lurker here. Finally made an account, this is my first post
At a few track days i noticed that even with the VDC turned off it intervenes in long sweepers and if i take the curbs harshly. There are three options to turn the VDC completely off

1. Pull the fuse (but also kill ABS)
2. Unplug Yaw Sensor (kinda permanent)
3. Install a switch (that's what I did)

I found a switch that is advertised for different Nissan models, just not for the 350Z, but it looked so similar that i took the chance and ordered it. It fit perfectly fine in the center console. Not sure if i am allowed to post links to products, will do an edit if allowed.
Anyway, installation was relatively easy. Needed a relay though to have the VDC Off when the switch is on and illuminated. That is not needed, i just wanted it that way. Also this is a switch that latches into position. No need to remember to turn of VDC before every Autocross run or track day session. So many times i have started an autocross run just to realize in the first turn that i forgot to turn VDC off, so I have to do it while driving. Needless to say that's dangerous and slows me down. Now with this switch i turn VDC off in the morning and turn it back on when i am driving home.

I hope this helps some racers out there. Let me know if you have any questions.

Love the label/graphic on the switch.

Good info. I know there's a few threads here that discuss "VDC off for real" but this looks like a really easy/clean way to go.

And yes, a link is fine since everyone is going to ask for it anyways....

 

Love the diagram. Good work. I just unplugged sensor because I never want it on

 

Yeah, can we get a link for that switch. This looks super nice.

 

Here the link: https://customswitches.com.au/produc...o-suit-nissan/
They are in Australia, so keep shipping cost and time in mind.

You might have also noticed that the colors are switched. They immediately sent me a new one when i showed them. I just haven't installed the replacement switch yet.

 

Nicely done! Did you use T-taps for the right or left seat switch for power and ground? In the pic above, it looks like the VDC OFF switch is illuminated and so is the seat warmer switch on the right but not the left. Is it just the lighting? Maybe a wire got cut instead of spliced?

 

I soldered everything. also added a small 2 pin connector for the power coming from the body to the relay and going to the yaw sensor. That way I can easily unplug the Center console if I need to take it out.

I took that picture of the illuminated switches on the bench with a power supply hocked up to only 2 of them. In the car all 3 are working as expected.
