Helping a friend install Slee sliders on his 2021 LC. He also bought the light kit from Slee which he'd like to have. He'd also like the lights to come on when the door is opened. The instructions seem to be for the Lexus version and so it talks about splicing to a harness that we cannot find. Anyone that has added the light kit to their sliders, where is the best place to pull power so the lights turn on when the doors open?
