The front seat belt and retractor in a two-door require you to first disconnect the negative
Battery Cable and let the capacitor in the restraint circuit discharge for a few minutes. Check every seat belt, buckle, mounting hardware, retractor, tether strap and anchor for correct installation and damage, replacing those that appear cut, frayed or torn and tightening all fasteners. To use the lower seat belt anchor, attach the seat belt and retractor to the B-pillar inside of the car so the hole in the B-pillar and the tab of the upper retractor bracket match up. Tighten the screw between the lower retractor bracket and seat belt lower anchor to the base of the inner B-pillar to 40 Nm (30 ft. lbs.), attach the yellow body wire harness connector to the seat belt tensioner initiator, route the seat belt webbing through the slot in the lower B-pillar trim and then put on the trim. Attach the top of the seat belt loop to the height adjustment on the upper sport bar, tighten that part with a 40 Nm screw to secure it and install a new trim cover over the turning loop. When securing the lower anchor for travel, do the same and fix it over the outboard side of the front seat's cushion frame, while tightening the fixing screw to 40 Nm (30 ft. lbs.). Do not put the positive battery cable back on until after finishing the test for the supplemental restraint system, following any service on these parts.
