Your Tahoe Police Package has grounding studs located at the lower driver's side and passenger's side rear compartment liftgate opening for connection to customer electrical equipment. A five foot (1.83 m) blunt cut length of #8 awg copper wire is coiled inside the jack storage compartment to permit grounding of electrical equipment that may be mounted forward in the rear compartment and behind the second row seatback. These grounding studs (SEO UT7) may have been ordered for your Tahoe Special Service Package.
