How To Use AlfaOBD On 2025+

[kraz]

I already have the rear LED tail lights installed, but they’re currently using the RetroShop harness. Could you share the headlight part numbers you have? From what I understand, there’s only one set?

We’ll need a harness too? I’ve heard the connectors are different.

Need custom wiring also, for both headlights and tail lights (retro shop harness won’t allow the animation to work).

Gotcha. Looks like I’ll have to wait a little longer for the harnesses to become available.

I can build those now.

Will this ever work for a Powerwagon?

Curious, would the OBDLink LX work to at least download the proxy configuration so I can send it too you for my Bighorn? I can certainly test my otofix d1 lite to test if it can keep the SGW open with a 1 month autoauth subscription.

If you do end up getting set up to perform the proxi alignment yourself, these are the steps in witech:
close witech, disconnect the device from the OBD port, turn truck off, open then close door, and let the truck sleep for 15 minutes.

I am ready to buy a TOPDON X3 or X7 to try this out with but currently on the TOPDON forums as early as yesterday people are complaining of having the active 3 day WITECH sub and it disconnecting with an internal error. Did you experience this using TOPDON? It seems the issue is on Witech's end not supporting TOPDON J2534 currently since about December.

A cheaper alternative is the wired X3 which is WItech 2.0 supported and it says it supports AlfaOBD. I am thinking to use the A30M with Auto Auth to keep the SGW unlocked and only the Topdon X3 to do the alfaobd configuration changes and then proxi align with a 3 day witech pass and the X3. However it seems they havent fixed whatever is not allowing TODON tools to work with Witech that just started a month ago. Any suggestions?

You should be able to READ anything without AutoAuth, its only needed to allow any writing. Try it. i know for my Xtool scanner even with autoauth I can read all data from all modules, I just cant perform any functions like clear codes etc.

I can certainly read the modules with my otofix, but it is my understanding to download the proxy configuration with alphaobd I would need to unlock the SGW (autoauth). Am I incorrect in this understanding?

Nope, you don’t need anything special, and no unlock necessary for reading things and creating backup files. Your LX will work (realistically, ANY reader that is compatible with alfaobd should work).

Same question for a 2025 2500 BH ?
I have AutoAuth and Launch X431 Pro 5 with J2534 , will try to see if it can unlock the SGW for AlphaOBD

I would think so. See if you can connect to the body computer as a grand Cherokee WL. If so, everything should be the same.

For a Laramie headlight, the led stripe at the top do you think it would be possible to have it on on the bright setting and only that while driving. Only way i can have it on bright setting is with headlight switch on auto and its day light outside with key on, truck running other lights come on under it. When you put headlight on it parks they dim and you need either bottom lights on or fogs (that might be a canadian drl thing)

Thanks for write up btw!

Is this on a 2025+ Laramie? I’m not aware of any LED strips on the 2025+ LED headlights that the Laramie uses.

 

[trev187]

Yes it's 2026 2500 Laramie, this stripe.

 

[trev187]

Oh my, just noticed this thread is on the 1500 section my bad

 

[Jimmy07]

I got the premium headlights and digital cluster swapped in and configured.
I pretty much have all the settings figured out for alfaobd, so I’ll work on a few posts listing all the settings associated with all the different features people might want to add.








And the animated lighting works too:

Wow, this is a great bit of work demonstrated here. It seems to be a bit overwhelming to make some simple changes. I guess OEM folks have achieved their goal, make all the changes you want, but you will still have to "kiss the ring."

Thank you for your efforts to figure this all out.

I think the word to the wise is buy one of the new trucks configured how you want, as it appears to be very expensive to retrofit in parts, equipment, time, and then off to the dealer and hope they do not screw up what you have done by accident.

There is a great potential for a business to make these changes for customers and offer these services cheaper than local dealer rates. I would guess once the equipment is paid for, your variable costs would be minimal. You could run this service out of your garage, which would allow you to be out of the weather, have access to electrical power, and minimize labor costs.

For me, I will keep what I have currently, a much shorter, well-documented learning curve for my current truck.

I can build those now.

Gotta ask, I currently do have the redesigned OEM led tails I got from the dealership and installed it with the RetroShop harness—6 months, no issues so far.

How much do you charge for the 25+ 1500 OEM led tail lights and headlights (from limited and above trims) harnesses if you’re still making them? Would the animation part require programming changes? I wouldn’t mind waiting on the animation part, if I can actually swap the reflector led headlights to the projector led ones (limited and above trims) for now, if possible?

I can PM you a price for the harness needed for the LED tail lights, but you have to do the programming with alfaobd to make them work.
For the animation, it’ll work with programming, but I’m not sure if the premium headlights must be installed or not in order for the tails to do the animation.
I’ve successfully installed and programmed the premium headlights (see my post two posts above), and the animation works without the tails being installed, but I believe the smart lighting module on the headlights is the master for that feature.
