First and foremost thank you Gunn Kim for helping me through this process! Super helpful and insightful guy in our group!

A run down of what this switch is:
It allows you to perform various actions such as:
- Brake boost
- Left foot brake
- Heel toe
- Standing burnouts
- This help tremendously with throttle response.
- What I’ve noticed is with the YAW sensor activated, (as well as stock throttle application), it takes some time to get throttle response after left foot braking. But by applying this “mod”, it pretty much eliminates any delay.
Key notes:
- It will throw a service light code but not for a very very long time, which is why I have it on a switch. You can also clear this code with a scanner and be good!
- Don’t worry it won’t put the car into limp mode either.
- You retain your brake lights so this is great for track, boosted, or hooligan applications.
- This does not work on +2016 370Z unfortunately 😞
- You can tune this out but in order for that to work, you need to retain your YAW sensor functions. But then comes the question “how do you get rid of traction control?” This switch is how!
Please let me know if you guys have any questions, I’d be happy to answer them to my best of my abilities. There wasn’t much information out there so I figured, let me add to it!
UPDATE: 2/29/2024
Here’s a little more information as far as what it does electronically. As per Phunk from the 370z forum:
“P1805 BRAKE SWITCH
Description: Brake switch signal is applied to the ECM through the stop lamp switch when the brake pedal is depressed. This signal is used mainly to decrease the engine speed when the vehicle is being driven.”
So I believe that what this wire (Brake Signal Wire/Switch) does is cut information being sent to the ECM saying that the brake pedal is being depressed. Since the actual stop lamp switch and brake light fuse are still intact, you still retain taillight and full braking force functionality. Below is Phunk’s summary:
“So in summary; You have 3 large connectors at the ECU. Find the one that matches the attached image and pin 122 is the pink wire for brake signal input. If you disconnect this wire, you can brake boost without losing your brake lights. But if you leave it disconnected too long you will get DTC Code P1805. This is why you would rather put a switch inline here rather than just cut the wire... so you can open the circuit when you want to brake boost without interference by the ECM, and then reconnect the signal later so you do not get the code. An alternative could be to disable P1805 in the ECM if you have UpRev. Which I think I might go ahead and do now next time I am in my ECU... then I can just de-pin terminal 122 without cutting the wire... to this day my cars wiring is all un-cut minus my injector sub-harness... prefer to keep it that way personally.”
