My instructions allow you to do it without removing the large piece of trim (which is the biggest pain). Most of the steps should be similar on X, as far as the back of the car is concerned.
I used a 10" long thick cable-tie that I had lying around and tied a string to it. I fished the string through the hard plastic piece. Once I had the string in there, I tied the blackvue cable to the other end and fished the cable through. It worked great and eliminated one really hard step.
Thank you vandacca for the great idea of using a cable-tie to fish a string. I am especially happy to hear that this can be done without the stress of removing the fragile cover. I now just have to wait until our temperature gets over -20 F.
Mine is a December 2017 build and I have it connected using the trailer brake connector. I don't believe that Tesla would delete the connector all together since all Model X's come standard with a towing package. If they don't provide you with the connector harness, you could always buy one for a few dollars.
I taped mine into the most right plug (with red+black wire). You can buy the cable here:
Actually I just peeled back the carpet on my 3/18 Model X and don’t see the tow connector.
Look at post #2 & #3 on this thread. There are pictures and part number for the harness. I would NOT cut any wires... but that's just me. Also you may have to look higher on the left hand side of the wheel well close to your left foot almost near the dash for the place to plug this pigtail in. That's where mine was ziptied. I don't have any pics to share ... sorry.
I’ll be just using wire nuts and connect to the pigtail. No cutting of any wires. Gonna just bring it into service and see if they can explain why I’m not seeing 12VI’m glad you found the pigtail. Bringing it in for service and having them look at it is the best option. This way you are not interfering/ altering the setup of the vehicle.
