Maintenance Tips and FAQ

  • Before purchasing and installing a socket assembly, make sure it’s the correct size and fit for your vehicle.
  • Are all bulb sockets the same? No. Some sockets have more contacts than others, depending on their function.
  • Is there a reason there’s grease in my old socket? Yes. It’s dielectric grease, which is designed to keep water out to protect the contacts from corrosion.
  • Does the ABS wheel-speed sensor harness need to be replaced when the sensor is replaced? No. The harness only needs to be replaced if it’s worn or cracked, or if the wire insulation is damaged.
  • Is an illuminated ABS light a possible sign of a malfunctioning wire harness? Yes. Your vehicle’s ABS light may illuminate for several reasons, and one potential cause is a malfunctioning wire harness.
  • Do all vehicles have ignition coil wires? No. Whether your vehicle has an ignition coil wire depends on the type of ignition system in your vehicle.
  • Are all ignition coil wires the same? No. Ignition coil wires come in different lengths with different boots at the ends.
  • Is the vapor canister vent solenoid harness weather-resistant? Yes. The harness helps protect the wires and pin connections from the elements.
  • Can a vent solenoid stick? Yes. A vent solenoid can stick open or closed, which may cause the Check Engine light to illuminate.
