2020 Model S Trailer wiring question

[xxaarraa]

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.
