Installation Notes and Tips

Installation of the Dorman 645-715 harness requires basic automotive electrical knowledge. Ensure the vehicle is off and the battery is disconnected before beginning. Remove the old wiring harness carefully to avoid damaging connectors or glow plugs. Match the female blade terminals to the corresponding male terminals on the glow plugs and power source. Verify the 9.94-inch length fits without strain or excess slack. Use dielectric grease on terminals if desired to improve corrosion resistance. After installation, test the glow plug circuit for proper operation before reassembling any engine covers.
