Hey, I've read through most of this thread and understand that zmnypit is the go to guy for harnesses. I have a 2015 Sierra Denali 1500 and want to swap both the headlights and taillights to the 2016 version. Someone hit my right side tail light today so I want to take this opportunity to swap to the new ones. What's the process involved in swapping the headlights and taillights? Is it a direct swap for fitment on both and then you just add harnesses from zmnypit?
Also most likely will be grabbing those XB fogs so thank you for that discount code as well.
