Hate to say but it's either a bad unit or something in the wiring. I installed the same brake controller 3 weeks ago and it lit right up immediately. Controller works and no dealer programming needed.

If I'm not mistaken, I believe you have to remove the trim around the radio and other dash components. Are you installing the Curt Spectrum brake controller?

I have a few questions regarding the 5100 shocks for front and rear of my 2020 Silverado 1500 RST 2WD. 1) If I'm not mistaken the 2wd and 4wd shocks are the same part? 2) If I am lifted with 4 inches in the front and 3 inches in the back with a Readylift kit, will this work for me? I wanted to upgrade both front and rear shocks for a better ride quality using 5100 series. Since I would be already lifted , I am not seeking any height increase just better ride handling. Will leaving the front shocks setting at 0, work for my application? 3)Since the rear would be lifted 3 inches by rear lift blocks, will I need shock extenders for the rear shock or will the 5100 be ok without an extender? 4) Does the 5100 front shock set at 0 already have some height increase over the stock height strut (shock)? These are my questions regarding the 5100 series shocks for my truck. Any help would be greatly appreciated. Sent from my Pixel 2 XL using Tapatalk

If I upgrade the front shocks to the Bilstein 5100s on my 2020 RST 2wd, will the preload spacer still fit on the shock and all other strut components from the lift? In other words is the body size of the Bilstein 5100 thicker than stock shocks on a 2wd? Sent from my Pixel 2 XL using Tapatalk

I agree.ready lift told me that the 2wd and 4wd models use different struts? Can anyone confirm this?

Ready lift is telling me this kit will not work on the 2wd . Anyone know why?

I've been curious on this kit. Readylift states 4wd ,however Im almost confident that this will work on 2wd as well? Any one know for sure?
