2020 Model S Trailer wiring question

This site may earn commission on affiliate links.
Trying to setup the 2020 S to tow a lightweight motorcycle trailer to haul a dirt bike. Installed a stealth ecohitch from torkcentral and while their packaging was poor and lot of hardware was missing when arrived, install went without a hitch (ha). I even kept my re-inforcement bar for 3rd row passengers.

I ordered the tekonsha wiring kit for trailer lights. Buddy and I can't figure out the right color wires in the 2020 to tap for brake light and turn signals. Anyone know? I found some previous threads, but they only refer to older Model S cars, as do all the youtube videos. None of the color wires mentioned in them match what I have in the 2020 tail light harness.

Help would be appreciated if anyone has done this before.

OK update - I used trial and error and found the left and right turn signal wires. They work consistently. The running light wire remains unconnected, however I am getting running lights consistently. The only issue is brake lights. I found a wire that triggers them but its inconsistent. They mostly come on when you brake, but sometimes they don't. At present I am getting around this by using a smart bicycle tail light that has an accelerometer built it. It just automatically brakes when it senses you are slowing down - wireless and rechargeable so I just have it zip tied to the trailer and its working well.

Model S makes a great light duty tow vehicle. I am doing about 375 wh/mile towing a single dirt bike and lightweight kendon trailer.

I attempted to follow the wiring diagram here, same Tekonsha kit, same needs. but couldn't get anything to register out of the tekonsha, no lights, no nothing.
Even tested with a trailer harness tester...

I'm about to follow up with a local guy who repairs Teslas, he looked up the 2020 Model S wires and gave me this info, hoping this can help someone else and me when I pull it back apart.. :

At the plug colors will be first color is wire color,second color is stripe.
Left tail lamp
White/red=Stop (brake lights)
Red/blue=left turn
Red/grey=taillight

Right tail lamp
Black/violet=stop
Yellow/white=turn
Brown/white=taillight

HTH,
And any feedback on troubleshooting the Tekonsha would be appreciated..
