They are completely plug and play with four wire hookup (switched power, constant power and ground connections required). Harnesses are designed with a sliding grommet seal and 4 - 5 feet of length from the rear of the cylinder head to the PCM mounting position under the vehicle dashboard. A sliding grommet seal allows for professional, leak proof installation.
