How to Install an Electrical Grounding Kit

In a car the normal pattern of electric current flows from positive to negative through the body of the vehicle. There are three areas where resistance to this flow of electric current occurs: connectors of the body, the transmission and the engine. When there is resistance the flow of electricity is disturbed, creating stress on the computer, lamps and spark plugs. A ground kit helps you get the highest level of performance out of the electrical system in your car.

Things You'll Need

  • Ratchet set with socket extension
  • Allen wrench set
  • Screwdriver set
  • Groundwire kit
  • Set the grounding kit wires out and check their gauge, seeing if the ends are gold plated and ring shaped. Grounding kit wires normally are 4 gauge. Each wire attaches with a screw that already is part of the car’s body assembly.

  • Add three ground wires to the negative battery terminal by unscrewing the terminal clamp with a screwdriver.

  • Run one ground wire to the fuse box near the headlights. Remove the screw,and attach the wire ground from the battery to the fuse box.

  • Take another ground wire from the battery, and attach it to the transmission. Use a rachet to remove the hex screw, and attach the ground wire to the transmission.

  • Arrange the third ground wire so it attaches to the right side of the engine block. Remove the screws and bolts, and lift the engine cover straight up.

  • Screw a new ground wire onto the right side of the engine block, and then run the wire to the left side of the engine and attach it to the engine block. To run this fourth ground wire from right to left, run it under the engine cover.

  • Attach the last ground wire to the engine block on the left side, and run it up to the underside of the power steering bracket. Connect the last ground wire to a gold or brass colored screw on the underside of the power steering column. Installation of the ground kit is complete. Reattach the engine cover.
