Running Wires -- 1989 560 SEL
I'm trying to run wires from the rear of my 1989 560 SEL to the dash for audio purposes, I'm not sure how to get them there. How do I access the wire tracks that would lead to the dash?
I see where the amp previously had wires going to it, do I just stick a wire in there and thread it through, hoping for the best? I've already taken out the back seat and liner, to access all the wiring, just need to figure out how to get it to the front.
