Roof Wiring
If the vehicle is equipped with option 6F5 as part of the police package Z56, an extra wiring harness is available for any roof-mounted aftermarket accessories. The harness begins under the right side of the instrument panel in a coil on the floor. The harness route then proceeds under the right front door sill plate, up the right B pillar, and across the roof bow. The harness loops 81.3 cm (32 in) to the rear of the windshield centerline.
