What are the 2005 chevy silverado ground wire locations?

The ground wires on a 2005 Chevy Silverado are located on the main engine block as well as the frame rails. A properly grounded electrical system is vital to the performance of Your vehicle. Ground the engine block to the vehicle body with a heavy ground wire or cable making sure that both connections are clean, tight and metal to metal. Each individual ground can be routed to a central location and all of the components in that general area can be grounded to it. Make sure that the wire or cable for each ground has enough length so that when the engine torques (moves under a load) the ground will not be pulled apart.
