My reply earlier only pertains to the LED headlamps. If you are ADDING fog lamps because you don’t have them from factory, then you need to add the harness and headlamp switch for them and enable a few more settings in AlfaOBD. If you have halogen factory fogs, and are swapping them for factory LED fogs, it is a direct plug n play swap, but you have to enable the LED fog lamp setting. The LED tail lamps have a 12-way connector on them, whereas the base tail lamps have a 6-way connector, so you’ll have to build little conversion harnesses for them using about $20 in parts. You’ll also need to enable the LED tail light settings for those.
EDIT: Since you already have AlfaOBD, you might as well just get the LED tails with blind spot sensors, and enable that feature too. It’s only a few wires that need to be added and is fairly simple.
so im doing this very thing on my 4.5Gen 2019 tradesman II 2500 6.7 crew cab. got a sweet deal locally from a guy with a laramie that swapped his headlights out for the black housing led's... so i bought his and installed them and they function 100% with key on truck off, as soon as i start truck up they flicker and shut off!
after many dealerships trying still no luck.
countless hours later i find write-ups on this for earlier trucks, but no conformation on the 19-20 hd trucks....
so lets get to the brass tacks, has anyone done the halogen to oem led upgrade without harness/butchering factory loom, and used alfaobd on a 19-20 hd truck?????
if so what connection setting do i use in alfa for a 19'-20' 2500/3500 ?
im sure i can figure out what settings to change, based on previous comments.
im just trying to verify personal experiences before wasting more $$$$ on this conversion. or just put the halogens back in and sulk..... lmao
all information welcome thanks
