I have a 2019 Mini Clubman S. I am attempting to install a wiring harness for a small trailer to pull my dads mobility scooter. I have been able to get the wiring for the left and right directional and I have lights on for the trailer when I turn on my Head Lights. Does anybody know what wire I can use for the brake lights ? I am just using a splicing connector to connect the wiring harness. I went to Mini here in Vegas and they told me it couldn't be done. Any help or advice would be greatly appreciated.

 

Look for the thread for the trailer hitch. It should talk about the wiring.....
