This is a very high quality replacement baro/temp sensor pigtail for 2004.5 and up Polaris Sportsman, RZR 700-800 EFI UTV's, ATVs. This harness features a brand new connector, vibration resistant wire, sealed splices to factory harness, and comprehensive and easy to follow installation instructions. The wire used in the factory harnesses and the vibration prone location of this sensor causes the wiring to fail in a very short period of time. Some of the symptoms of a bad harness are a "Check Engine" light and ECU codes of 41 and or 45, or intermittent rough idle speeds. This harness solves the common problem these ATVs have with broken factory wiring harnesses on the baro/temp sensor.
