Reverse trigger wire

Hi, I just ordered the

$163 wolfbox g900 rear view mirror camera, mirror dash cam 4K front and 2.5K rear, smart full 12’’ touch screen, backup camera for car, GPS, WDR, night vision, included 64GB card

wolfbox g900 pro dashcam reverse mirror camera. I will be installing the rear camera on the inside of the rear window looking back. It would be nice to know where I can connect the reverse trigger wire inside the cabin without having to go to the reverse lights or tow hitch. Is there a reasonably easy location inside the cabin. Any help is greatly appreciated.

 

I am not understanding which pin this is and how do you access it?

 

Remove the radio and find the connector on the radio that looks like J33. You’d be splicing in or building a t harness. Splice into pin 5 or 17 on that connector.

 

Maybe a stereo shop should do the work with info supplied

 

This harness would be ideal for tapping the reverse wire without cutting the OEM harness.

Thank you for all the replies

 

You gonna show what you did (or gonna do)?

 

I just ordered the sonic beat adapter. Once I do it, I will post some photos. I am still also waiting on the mirror to arrive

 

You know how to remove the head unit?

 

I just saw this video. Hopefully it goes easy when I am ready to do it.

Cool!

 

I am not sure though how I will route all the wires to completely hide them. I imagine once I lift the carpet I will find a place.

 

carpet? Is it a substitute for the interior rearview mirror?

 

Yes, so I know I will run it under the headliner towards to the passenger door then down along the A Pilar. After that point how to get it back to the dash I am not sure.

 

Ok, lots of items to get access the space. My bad.

 

Check this video, it shows the removal of head unit and also the room behind the dash.

My opinion is the reverse trigger on the wolfbox camera is mostly useless. It will put a grid on your rear view mirror to use as a grid like on a back up camera.

The better solution is honestly to either use the factory reverse camera for reversing duties, and/or relocate it if necessary (if you have stuff in the way). The wolfbox camera IS GREAT for rear view mirror duties.

(3rd gen Tacoma with alucab camper shell and a swingout and a 35" tire mostly even blocking the wolfbox camera and it's still useful)

 

You say this turns it into an encumbrance?
