Many individuals do their own DIY bypass parking brake wire installation, but some hire a professional. Continue reading to learn how to get around the bypass radio parking brake.
Many people fail to ground the brake wire or connect it properly. Read on to learn how to do it correctly.
What Is A Parking Brake Wire?
The android head unit in the car is to be signaled via the brake wire.
It comprises a wire that connects solely to the amp remote wire and parking brake wire at the back of the radio, as well as a wire that supplies power and grounds.
These devices are used for radios that employ an on/off/on sequence to verify that the e-brake is applied.
Direct connection to the ground is possible with simpler radios looking for a ground signal via the park brake radio line.
If you require the true bypass, you must understand the signal type the radio is looking for.
How To Bypass Parking Brake Wire?
Parking brake mode has been included to discourage drivers from watching movies while driving. Driving and watching DVDs at the same time is dangerous.
The methods for bypassing parking brake wires are shown below. Parking brake bypass then won’t be a problem.
Grounding The Head Unit Of The DVD Player
It is a common technique for DVD players connected to the brake interlock system. The technique is also applicable to aftermarket DVD models. Remember to turn the ignition off before starting.
- Utilizing the removal tools, remove the plastic trim from the head unit. To access the two screws holding that trim surround, pull up the left side just enough.
Pull the radio out of the din slot and away from the dash after loosening the trims’ attachment point. - Find the green wire and the black wire. It is the black ground wire 12-volt at the back of the head unit. Consult the DVD player’s user manual if you need clarification.
- From the brake interlock system, disconnect the parking brake cable. You can also chop it off at the midpoint.
Use electrical tape to wrap the remaining end. You must strip the parking brake wire’s head unit end to reveal the ends. - Obtain the ground wire that joins the car’s chassis to the DVD player head unit. Then, split it in two. Remove the ground wire’s two ends.
Ensure you remove the insulation from the three ends, leaving the wires exposed by between 1/4 and 1/2 inches. - Use sturdy tape to join the wire’s exposed ends. Around each connection point, put another layer.
- Use the screws you removed to mount your car’s head unit after you’ve mounted it.
Before starting the vehicle, install one side of the plastic bracket and then the other. If everything goes as planned, this should work.
Some DVD players can recognize hacks and temporarily halt video playback. If the radio continued to function after bypassing and stopping, this might be the problem.
Using Toggle Switch
The second method we use involves installing a little switch. Any momentary toggle switch is acceptable. You might use a toggle switch to bypass the parking brake when driving.
- Utilizing the removal tools, remove the plastic trim from the head unit. To access the two screws holding that trim surround, pull up the left side just enough.
Pull the radio out of the din slot and away from the dash after loosening the trims’ attachment point. - Find the green wire and the black wire. It is the black ground wire 12volt ground at the back of the head unit. Consult the DVD player’s user manual if you need clarification.
- From the interlock system, disconnect the parking brake cable. You can also chop it off at the midpoint.
Use electrical tape to wrap the remaining end. You must strip the parking brake wire’s head unit end to reveal the ends. - Obtain the ground wire that joins the car’s chassis to the DVD player head unit. Then, split it in two.
Remove the ground wire’s two ends. Ensure you remove the insulation from the three ends, leaving the wires exposed by between 1/4 and 1/2 inches. - Connect the toggle switch’s one end to the head unit’s parking brake wire. You should connect the other end wire to the ground.
The stereo player may now be replaced, the trim cover secured, and you can ensure the toggle switch is visible and reachable. - Flip the toggle switch off to stop watching a video while driving. The parking brake bypass switch is what it is. Drive your vehicle for a while before turning the switch back on.
Using Relay
Installing a relay is necessary to help circumvent the parking brake on more recent pioneer models. You must first obtain the proper relay switch.
- Eliminate the amplifier’s remote ground signal cable connection. After that, join it to the power pin of the relay.
- Connect a ground wire to the coil’s one side. The car chassis can be linked to all ground connections.
- Pick up a second ground wire. Run it from the open contact after that.
- Connect pin 30 on the relay switch with the pink or green parking brake cable. The connection type will be an open circuit until the boss DVD player is turned on.
- After being turned on, the device will check the parking brake wire before turning on the remote power. The amp will then turn on and trip the relay switch after that.
The relay switch will discharge ground onto the parking brake cable when triggered. The parking brake sensor is disregarded whenever the DVD player model is turned on.
FAQs
What Does The Parking Brake Do On A Car Stereo?
The purpose of a parking brake is to prevent your car from rolling while parked. The brake pedal must be applied every time you park a manual gearbox vehicle.
You should connect the parking brake wire to the handbrake. The handbrake must be engaged to watch TV or a DVD, which is a precaution.
For the audio to flip to the reverse screen when the car is in reverse, it needs a 12V source. The screen will dim or brighten when the vehicle’s lights are turned on, so be sure it is linked to the lighting circuit.
Where Is The Parking Brake Wire Located?
There is a green parking brake wire in the pioneer harness. Look for the parking brake by the driver’s footwell.
You’ll see a little parking brake switch on top of the brake that releases when the brake is applied.
The top of that switch will have a single wire wrapped in a plastic weave. They are referring to that cable.
A wire harness is connected to the parking brake pedal, and it’s necessary to tap the ground wire.
Follow the cables up for better access because tapping straight at the connection could be challenging.
Is Parking Brake And Emergency Brake The Same?
The parking brake is the emergency brake in most vehicles. Both are auxiliary brake systems, which operate independently of the hydraulic system activated when the brake pedal is depressed.
It functions the same whether it is referred to as an emergency brake or a parking brake.
While the brake pedal allows you to gently and gradually apply pressure to stop your car, emergency brake systems are more forceful.
The brakes you use to keep the car still while parked are called parking brakes.
When you press the middle pedal and nothing happens, you can rely on the emergency brake to stop you. They are the same in most autos.
Conclusion
You now understand how to bypass parking brake wire.
Once the parking brake has been disengaged, you can use the brake wire car stereo and watch videos on the video screen while driving.
While we hope you can now bypass the parking brake wire, it is not a good idea to do so while driving.
