In-line fuse on power harness assures longevity of air pump in case of electrical short. Can be combined with automotive lumbar supports and seat heaters for the ultimate in driving comfort. Note: These kits are designed to be universal, however, prior to installing the unit, please inspect the seat construction to determine if you will need a front or rear mount lumbar prior to installing the unit.
