ok - well I was willing to try the SLT grill with the AT4 trim piece - but if I have to order it all together I can live with that - lol. I may have missed it - but what is the part # for the whole grill assembly? Appreciate the help!
Guys - looking to do the same on my black SLT. So you posted the black hood trim piece - thank you. What about the black trim piece that goes around the other 3 sides of the grill? mine is chrome but if you know that part # I'd was hoping you could share it and any info on the install???
thanks
Brian
I had the exact same issue on 2020 2500 Sierra. Just replaced with this harness and plug from etrailer. Everything works!
