Hello, was looking at putting in the ac vents into my knee pads on the drivers side to the left and right of the steering wheel. I was wondering if someone whom has already done this can help me with how did you route the new ac duct work? Does it all come of the same side hole of the box area ( where the hose comes off of now for the door vent) and I am guessing you would use some type of splitter to hook the new duct work into so it can go to all three vents? Appreciate any info you can offer. Thank you
