The wire harness to the T-map sensor is a well known issue on Polaris EFI machines. It will vibrate over time and break the wires either internally or externally and can be hard to diagnose. Many times it will throw a code but not always. Fix it now with our own version of the Polaris 2875542 and 2878494 harness repair kit. Simply cut off the old harness and use the included butt connectors or solder the connections to the new pigtail. Our pigtail fits perfectly to the T-map sensor and has a nice waterproof boot protecting the wires going into the plug. Fits the models listed below using the Bosch 4-wire T-map sensors (2410422, 2411528 and 2411082): 2012-18 RZR 570 2008-14 RZR 800 (All Models) 2015-18 RZR 900 (All Models) 2014-18 RZR 1000 (All Models) 2016-18 RZR Turbo (Only Fits Air Intake Duct T-Map) 2014-18 Sportsman 570 (All models) 2004-07 Sportsman 700 EFI models 2005-14 Sportsman 800 (All models) 2009-18 Sportsman 850 XP (All models) 2005-09 Ranger 700 (All) 2005-14 Ranger 800 (All) 2013-18 Ranger 900 (All) 2013-18 Scrambler 850/1000 models 2014-16 ACE 325 2015-18 ACE 570 2016-18 ACE 900
