Remove the air line manifold from its connection point in 
the rear wheel well. Bring the manifold forward just behind 
the rear shock. The supply line needs to be swapped on the 
manifold with the line to the driver side shock. Remove the 
clips from the ends and swap the two lines. Use a drill with 
a 15/64” drill bit and drill a hole into the plastic liner and 
insert the manifold into it. Use two of the supplied 8” zip 
ties and attach the ABS & Electrical lines to the shock 
extension. Use two of the supplied 14” zip ties and attach 
the ABS line to the shock ABOVE THE SHOCK 
BLADDER. SEE PHOTOS
