2019 TailLights

Are they same as 2018 4th gen tailights

The taillights on the 2019- and newer Gen5 1500s are different than the Gen4 2009-2018(and 2019-20 Classic version trucks). From what I understand the 2019-20 2500/3500 taillights will fit on the Gen4 body trucks.

To add to what crash68 said, the HD tails will fit in the 4th gens, but the wiring and BCM configuration is different. The new tail lights have separated lighting, so the the turn signals are separate from the brake lights, and have the extra turn signal wires coming from the BCM.

I already knew that those newer tail lights had separate brake lights from the turn signal lights but if you was to get a set of those and put them in a fourth GEN truck that had the tail lights where the turn signals and the brake lights were on the same circuit, how do you hook those up if there’s not a separate, more than likely brake light wire coming to its own spot in the existing tail light harness?

It’s just like on my semi; the tail lights Yeah go ahead copy I’m looking back on our wayon the back of the truck have the combined brake light and turn signal but on the back of my trailer, petty much every semi-trailer, the brake lights and the turn signals are separate from each other.

I don’t know how they do it, but I’m assuming that there’s gotta be another wire that’s hooked to the brake light switch that’s coming from the truck that only goes to the pigtail for the trailer but does not go to the back of the truck. If I was to go to a separate brake light/turn signal light on the back of my truck I’d have to be searching around on the frame rail to find a wire to tap into. What would it involve on my pick up if I was to do virtually the same thing?

It’s pretty easy. Add the missing turn signal wires from the BCM, and use AlfaOBD- https://www.ramforum.com/threads/2019-hd-tail-lights-in-a-4th-gen.151018/

Oh, it involves running a whole new wire and that Alpha OBD thing, huh?.....hmm. I was hoping maybe there was an adapter or something that you could buy that would separate the two signals right there at the tail light just like how- I don’t know if you still can or not but way back in the day I saw a trailer wiring kit for like if you were going to hook up trailer lights to a vehicle that already had the separate brake lights from the turn signals, it came with a little adapter module thing that somehow combined the two circuits into one wire so that the trailer lights would work properly being that most passenger vehicle trailers are wired just the same way as most cars where the brake light and the turn signal lights share the same wire.

You could do that, too, with the curt trailer module, but you’d also have to stack a switchback module on top of that so the brake light will drop out when the turn signal is used. Retroshop offers a kit for it, but it’s crazy expensive.

Oh, I’m sure it is because I would imagine that there wouldn’t be much call for something like that to be used for anything else except for what it was made for which was to convert your four-wire harness to I guess a five-wire.
