Howzit Phil. I came across your videos on YouTube and you led me to this forum for more info. Read through this thread and I feel more confident now in upgrading my mirrors.
Specs:
2017 Silverado 1500, 5.3L flex, Crew Cab, LT, Texas Edition
Power adjustable mirrors
Manually folding
Goal:
Upgrade to DL8 mirrors with blinker in glass
-or-
Upgrade to black tow mirrors from 1Aauto with blinker in glass, puddle lamp, cargo light, and running amber LED's on the front.
(No need for power folding, auto dimming, or heat)
Please advise if goal is achievable with your custom made harnesses or DIY kits. Thanks in advance.
