Which Trailer Wiring Harness is Needed to Install Curt Triflex in 2020 Chevy Silverado 1500


Just bought a new truck see above and want to know can I use the Curt 51140 from my 2017 Chevy Silverado. Double Cab If so, is the same wiring harness useable on the 2020?


Expert Reply:

The Curt TriFlex # C51140 that you have can be used in your new 2020 Chevy Silverado 1500 but you will need a new harness as there where some changes between the 2017 and 2020 models. So what you'd need is just the part # C51525 and you'd be set!
