AEM Plug & Pin Kits essentially allow you to "start over" with your harness to create a new harness or replace your existing factory harness using new plugs and pins. Each kit includes four (4) OEM-quality plugs and all the OEM-quality pins you will need to re-wire the harness to the EMS. Individual connector kits, Bosch injector kits, and Bosch 4.2 LSU Wideband connector kits are also available. See the Purchase tab for available Plug & Pin and Connector Kits for Series 2 EMS systems.
