My wiring harness has arrived from absolut5 and I’ve seen a video on how to remove the head to get to the back of that back I think the cabling for my amp and speaker run needs to go down the middle and under the mat to get to the seats. Looking at the dash it looks like the gear coveoght need to come out to get to the mat edge. Anybody done this yet on a t6.1? Also any advice on the t6.1 a pillar removal would be great. Many thanks.
