Help - how to remove the backs of the passenger and driver seats?
They are current blank, whereas in certain cars I've seen the exclusive trim (with a little wooden trim across the top w/ photo below ).
I want to add this part to the car and there is also a little LED light that's under the wooden trim.
My question is has anyone done this installation? How can this be retrofitted and where do I get power supply for the new LED light strip under the wooden trim?
