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): FITS THE FOLLOWING MODEL(S): 2017-'21 ACE 150 2014-'15 SPORTSMAN ACE 325 2016 ACE 325 2017-'19 ACE 500 2015 SPORTSMAN ACE 570 2016-'19 ACE 570 2016-'19 ACE 900 2005-'09 RANGER 700 2008-'09 RANGER CREW 700 2010-'16 RANGER 800 2010-'14 RANGER CREW 800 2013-'19 RANGER XP 900 2014-'19 RANGER CREW 900 2012-'20 RZR 570 2021-'22 RZR TRAIL 570 2008-'14 RZR 800 2010-'14 RZR 4 800 2009-'14 RZR S 800 2015-'18 RZR 4 900 2015-'20 RZR 900 2021-'25 RZR TRAIL 900 2020-'25 RZR TRAIL S 900 2016-'21 RZR XP (Only Fits Air Intake Duct T-Map) 2016-'21 RZR XP 4 (Only Fits Air Intake Duct T-Map) 2022-'24 RZR TURBO R (Only Fits Air Intake Duct T-Map) 2022-'24 RZR TURBO R 4 (Only Fits Air Intake Duct T-Map) 2020-'21 RZR TURBO S (Only Fits Air Intake Duct T-Map) 2020-'21 RZR TURBO S 4 (Only Fits Air Intake Duct T-Map) 2014-'25 RZR XP 1000 2014-'25 RZR XP 4 1000 2013-'25 SCRAMBLER 850 2014-'25 SCRAMBLER XP 1000 2016-'25 SPORTSMAN 450 HO 2014-'25 SPORTSMAN 570 2014-'25 SPORTSMAN TOURING 570 2015-'21 SPORTSMAN X2 570 2005-'07 SPORTSMAN 700 2008 SPORTSMAN X2 700 2005-'14 SPORTSMAN 800 2008-'09 SPORTSMAN TOURING 800 2007-'09 SPORTSMAN X2 800 2009-'14 SPORTSMAN XP 850 2014-'25 SPORTSMAN 850 2010-'25 SPORTSMAN TOURING 850 2011 SPORTSMAN X2 850 2015-'25 SPORTSMAN XP 1000 2015-'25 SPORTSMAN TOURING 1000
