Rear Parking Sensors and Bike Racks

I have two electric bikes that I like to take with me when I go to New Orleans from Atlanta.

I have a fancy bike rack that attaches to the tow port and works great.

The only problem I have is that the bikes trigger the parking sensor and cause problems. Reversing with the bikes is an exercise in cacophony.

I was wondering if there was any way to remove the existing sensors and add convenient quick-connect electrical fittings that would allow me to extend the motion sensors to the other side of the bike rack. So when I wanted to use the bike rack, I would just pop out the sensors, plug in an extension cord that routed the cable through the bike rack and allowed me to plug the motion sensors into the bike rack.

I realize this will mess up parking, but it might solve the motion problem.

Also, could the same or similar be done with the camera? Could I add a second camera and a toggle that would allow me to switch reverse cameras between OEM and my custom one for my bike rack? And finally, what about brake lights? Could I add brake lights to my bike rack so people could know when I was breaking by splicing into the existing brake light cables?

Let me know if anyone has done this or what you think about this kind of customization. Thanks

To answer your question.. you can actually shut off the park assist feature if the sensors bother you too much.

I mean, you can definitely remove the sensors and spice additional wires to the sensors, but the park assist calculation will never work right with the reverse camera. Also, why change the OE parts permanently? What if you don't ride your bike later on?

I am sure you can run a portable brake light by connecting the wires to the original brake light. It would be pretty easy to do so.

For the camera, you can easily get a portable reverse camera for cars. A lot of them can be installed on a special license plate frame, clean and simple. A lot of them come with a small screens to be installed on the dash.

For myself, I just don't like messing with OE electrical wires. I would choose to use after market accessories instead of tapping into OE wires.

Hope it helps.

^ x2.

Additionally, you could stick these on the fancy rack..

I'd probably shorten the wires if it was just used for the rack.

Thanks for your reply. Sorry it has taken me forever to respond, I never got a notice.

What I was hoping to accomplish was to take advantage of the existing sensor system, but just extending the sensors and camera by about a foot. In other words, I was hoping that I could rig something that I could extend the sensors and camera temporarily while the bike rack was used only.

This would still give me the benefit of the lane change indicators working, the parking indicators, etc. I would still be able to use the reverse camera and it would supposedly notify me if I was about to run over a small child in reverse, for example. I figured the quick connects would allow me to remove the extensions and use it like nothing had changed.

I have heard that the factory-installed tow package has some method of modifying the alerts when a trailer or something is attached. I bought a new Jeep Grand Cherokee High Altitude with the tow package for this reason and hopefully can find a solution using the factory-provided wiring harness. Thanks for your reply.

I just picked up a 2021 Trailhawk and had this same experience. I was able to figure out where to turn off the brake assist feature, but I haven't been able to find where to turn off the sound.... anyone know?

well, if you turned off the park assist, via the button to the left of the " hazard" button, it should all be off - no park assist beeping
