Questions/Concerns Answered With My 5th Gen Taillights in my 4th Gen Ram

READ DESCRIPTION FOR MORE INFO
This video is meant to answer some basic questions with the set up I have. I bought my stuff from the Retroshop.us. I bought the painted taillights and the 7 pin plug and play wiring harness through them. It is high quality and super easy to install. Even for a person who doesn't really know what they are doing. But because its plug and play there is one Issue.
The taillights causes a bulb out indicator so I used an app called Alpha OBD to program out all the bulb out errors on my truck. The harness is a great high quality harness with one flaw. It uses a relay so the tail light can display the turn signal as well as the brake light. This creates a timing issue of the turn signals. Its pretty distracting especially when you are stopped at a red light, turning, at night time.
There are people out there that are on the 4th Gen Rams facebook pages and the Ram Forums that make these harnesses for less money, and they fix the only concern that I have stumbled across. They are not plug and play.
Other than that, the setup is an amazing setup. It looks amazing and turns heads.
Don't hesitate to ask any questions, I will try my best to get back to to you in the comments.
This forum is a really detailed way if you want to wire the tails up yourself and actually tie them into your body control module. Then they will work like the factory!!

The front blinker and BACK tail light blinker signaling at different times is PRETTY SWEET to me...I wouldn’t mind🐏

[@6234christian]

Haha a few people said that. Well at the end of the day it doesn't bother me anymore lol. It still works and looks sick lol.

[@americaskitchentable107]

I would think it would grab other drivers attention which is never a bad thing

[@paulwarren1586]

I added these taillights to my 2012 RAM 2500 CTD, I had to add load resistors to the stock harness because of the hyper flash even with the harness from the Retro Shop, now they work like a charm, yeah, I get some out of timing with the brake lights with the turn signals but that doesn't bother me, now I have figure out why my fog lights don't work, they did before the new taillights.

[@6234christian]

Hey Paul!! There's an app called alpha obd which can change all the power outputs on the tuck to managed led/hid so you don't need the resistors. Everything in this truck to led with no resistors or capacitors and I haven't had any issues. The only issue I had was the out of timing tails , but that doesn't bother me anymore lol.

@@6234christian You said Only 2500/3500 5th gen tail lights will work on my 3500 4th gen? I thought they were all the same tail lights??

[@BrokenAdam770]

In Europe, the brake lights and LED turn signals on the 5th generation RAM are separated. The brake lights on top and the turn signals are at the bottom.😊

[@miguelitomigra543]

I have a '17 Ram 2500, Alpharex Nova Headlights and 5th gen tails from Two Three designs. I got a "Parking Light Error" every time I used the turn signals with lights on. I used AlfaOBD to change from incandescent bulbs to LED and haven't received an error code since. And my lights flash in unison FWIW with no hyperflashing. In my experience most of the problems came from the headlights, I've had several sets. I recommend plugging regular incandescent bulbs in the front (without resistors) and see if the issues continue. If so, you know what the issue probably is.

There is a app you can down load to a laptop or your phone along with a programmer that yu plug into your truck and you can go in and set your truck up to allow leds to work properly.

[@joe7528]

If it has a resistors on the hardness and you done the AlphaOBD that could be the issue the resistors are over riding the Alpha program...... once you do the Alpha program you don't need resistors or any other canbus modules the resistors are causing the power delay since the power has to go through them and then send it out and that's causing your delay

[@6234christian]

That makes sense. I really don't thing there are any resistors in the harness. Everything operates normally. The only issue is the delay, that in only caused when I hit the break pedal

[@joe7528]

@@6234christian get a hold of the company that made the hardness and see if they added resistors if so that's the problem..... also make sure you correctly set the tail lights in the AlphaOBD some times it takes a few tries before it makes the changes

[@rooness9]

What year 5th gen taillights are you using? Are they 1500 or 2500 model? Also where did you buy them? Thanks! Truck looks great!

[@6234christian]

2019 and they have to be out of a 2500 or 3500 hd pickup to fit!! Thanks for the compliment!!

[@Moment2Forever]

I love my 4th gen oem leds, ones starting to die so I was thinking about this but the price tag is just too much for a slightly upgraded modern look, at least for me anyways

[@chasecotham9187]

what brand did you use for the tail lights and the harness? if it was retro shop do you know if the harness would work on the tail lights if i got them from a different brand?

[@cornyloewen3711]

So I just installed mine and I got my harness from ess k customs from Saskatchewan and it's 100% the same but I still have hyper flash on both sides but im wondering if it has something to do with the light strip I got hard wired to the left tail light that it would make both sides hyper flash????

[@cornyloewen3711]

Where can i get the cheaper wire harness cus im from Canada 🇨🇦 i have the tails just need the wire harness

[@jtrut6365]

Thank you!

[@6234christian]

No problem JT!!

[@quintenrose8642]

How do you use the app to clear the light? I have the same setup and it blinks fast with all those error messages.

[@6234christian]

I believe it was Chmsl led lamp present and brake light led present

[@changchung]

Mine harness cut the red off to leave the amber flash alone with turn signal.

[@6234christian]

Can I see how yours operates? Whats your harness like?

[@elgamazacatecas6670]

Wen u do the change on the light even u put plug an play u get warning lights.?

[@6234christian]

Yes. The truck is looking for a certain resistance in a halogen bulb. Once its led it has a different resistance causing an the computer to trip and tell you your bulb is out. But you can program it with alpha obd so the computer thinks is normal.

[@mr.confused5137]

What if I already have led tail lights same setup?

[@6234christian]

Then you have the cool new rams lol

[@eddieirizarry2550]

What headlights are you using?

[@6234christian]

I'm running the morimotos xb led v2s

[@Vicky-Hugh-Martini]

That is the same issue I'm having on my 2016 1500, so I'm currently using halogen tails (with LED bulbs) for now. The link I provide mentions of a BCM limitation on certain year models but yours might work. www.ramforum.com/threads/2019-hd-tail-lights-in-a-4th-gen.151018/

Oh sweeet. I got to put some wires into my bcm!!! Thats a great forum. Im going to put that in the description!!!
