Question:

Would this installation have any phantom power draw on my 2021 Kia Telluride when not in use? Tekonsha Prodigy P3 Trailer Brake Controller - 1 to 4 Axles - Proportional? Tekonsha Plug-In Wiring Adapter for Electric Brake Controllers Part Numbers: 90195, TK78VR Thanks

Yes, it would. The Prodigy P3 Brake Controller item # 90195 is never really off it just goes into sleep mode. When in sleep mode it's drawing milliamps of power which would take your Kia sitting idle for months to drain your battery. I have the P2 item # 90885 installed in a truck that sits for weeks at a time outside in the cold during the winter and have never had a starting issue.

If you are concerned it is really simple to unplug the Tekonsha Plug-In Wiring Adapter item # TK78VR when you are not towing. It needs to be plugged in to draw power so the adapter just sitting there unplugged would address your concerns.
