Hello, I'm newer to aftermarket parts/mods, and am looking for guidance. I bought a pair of "alpharex LUXX series" tail lights for my 2017 Sierra 1500 SLT . When I bought them I didn't realize they were not compatible with the SLT models factory led taillights, and was wondering if anyone could point me in the right direction as far as if there is an aftermarket harness or adapter I can purchase that would allow these tails to run. Any websites for parts or more info is greatly appreciated.
