Blind Spot and Tailgate Button

[geswek]

I have a 23’ 1500 LTZ with 7k miles.

i installed a Putco blade on the back and removed the tailgate (unplug the harness and camera.) The blade was the one that comes with the plug in play harness where you disconnect the taillights and put them inline. 
 

Ever since this I am having issues where my mirror blind spots will stay yellow for a long period of time. And my tailgate button will not lower or raise (this is the button on the actual tailgate—the one inside the truck is fine.)

 

Has anyone installed a blade and had this issue? I’m about to disconnect the blade and see if that changes. Otherwise I need to head to the dealer. The weird part is my backup camera and sensors work just fine. I just seem to randomly lose my blind spot sensors and the tailgate button. I was very careful when I undid the harness and removed the tailgate from the truck. I made sure not to break anything.
 

This is what I installed: https://www.putco.com/product/blade-tailgate-light-bar-plug-n-play/v/Chevy/Silverado 1500/2023/

 

Thanks for any help!

Just got home and pulled the connections for the putco, no change. Couldn’t release the tailgate.

 

i pulled the black plug apart (main connector for entire harness in the tailgate) and plugged it back in—now it works………

 

I’m at a lost. The connector only goes on one way. It’s not complicated so unsure why this is happening.

 

May have to take it to the dealer.
