the strips are mounted on aluminum rings one strip on the outer circumference one on the inner. 4 rings total which are mounted with L brackets to the metal dust shield in the wheel well of my car. The two strips to each wheel are wired together not end to end but just. the begining of each strip. all 4 wheels are then combined down to one wire since I was using 18 gauge. I found the screw terminals in PB to small to shove any more than 1 wire into. Set the total pixels to 200 in the mapper tab in pb so all eight strips run simultaneously like if they were one strip.
