If you are a drag racer, then you know the importance of a transbrake button. It allows you to hold the car on the starting line and launch at full throttle. However, wiring a transbrake button can be confusing, especially if you are new to racing. In this article, we will guide you through the process of wiring a transbrake button and provide you with a detailed diagram.
What is a Transbrake Button?
A transbrake button is a momentary switch used to activate the transbrake solenoid. When you press the button, the solenoid locks the transmission in place, allowing you to rev the engine without moving the car. This gives you an edge over your opponent at the starting line.
The transbrake button is usually mounted on the steering wheel or shifter, making it easy to access while driving.
How to Wire a Transbrake Button?
Wiring a transbrake button is a simple process, but it requires some basic knowledge of electrical wiring. Here are the steps to wire a transbrake button:
- Disconnect the negative battery cable from the battery.
- Locate the transbrake solenoid. It is usually located on the transmission case near the shifter.
- Identify the two wires coming out of the solenoid. One wire should be connected to the transmission wiring harness, and the other wire should be connected to ground.
- Cut the wire that is connected to the transmission wiring harness. Strip the end of the wire and twist it together with one end of the wire coming from the transbrake button.
- Connect the other end of the wire coming from the transbrake button to a 12-volt power source. You can use a switched ignition wire or a separate relay.
- Connect the wire that is connected to ground to a good chassis ground.
- Reconnect the negative battery cable to the battery.

Frequently Asked Questions (FAQ)
1. What is the purpose of a transbrake?
A transbrake locks the transmission in place, allowing you to rev the engine without moving the car. This gives you an edge over your opponent at the starting line.
2. Where is the transbrake solenoid located?
The transbrake solenoid is usually located on the transmission case near the shifter.
No, you cannot use a toggle switch for the transbrake button. A momentary switch is required to activate the transbrake solenoid.
No, you cannot wire the transbrake button directly to the battery. It must be wired through a 12-volt power source that is activated by the ignition switch.
You should use at least 14-gauge wire for the transbrake button. This will ensure that there is enough current flow to activate the transbrake solenoid.
Conclusion
Wiring a transbrake button is a simple process that can give you a significant advantage on the drag strip. By following the steps and wiring diagram provided in this article, you can wire a transbrake button with ease.
