Hello there. I have a 2015 Silverado 1500 LT with the towing package but it doesnt have the "trailer brake". Can i just buy the sensor and attach it myself?

 

i think the 2014 and 2015 will be the same i would contact e trailer . com they should have every thing you need and may have a video you can watch on the installation or can put it in for you.

what you need is called a brake controller. tekonsha makes the best units imo.
the mentioned etrailer site is fantastic

 

Im trying to stay away from aftermarket parts. I know they do the job but i rather oem. Anyone tried a oem version

 

the factory integrated controllers are expensive ,only work some times ,and dont show me a good value for the money . i have had a drawtite activator II installed in my 01 2500 hd for 14 years with out a hitch .it all comes down to quality of part's and installation . the after market company's have some good stuff out there .
