Did you ever get the LED light strip to work? If so, which fuse did you use? I’m looking to install a LED light strip between the hood and grill but can’t find a fuse that comes on with ACC. All the install videos show an outdated fuse boxThis is my first post I make, so forgive me if this is the wrong thread to ask this question in, but I'm trying to install LED strips in my 2021 Ram 1500 Bighorn and after looking over HAL9001's amazing diagram, I was going to choose F54B to use a fuse tap on because it only works when the truck is ACC/RUN. My question is, do I have to make sure I insert the fuse tap in the right direction? Is there power only through the middle slot, or is it just the outside slots? Sorry if my question is confusing, any clarification is helpful.
See post #27, and FYI, that is on the Interior Panel, not under the hood.I know this is kind of an old channel, but can anyone tell me which fuse protects the 12vdc outlet on the dash of the 21 Ram 1500?
F54A exists if you pull F54B and shift it from the right (B position) to the left (A position). F54B is ignition fed. F54A is battery fed. So, if you need one or the other, you have that option.I posted a diagram for the Internal Fuse Panel recently. This was good information to share with other 5th-Gen 1500 owners because the owner's manual doesn't contain such a diagram and the labels on the panel are very hard to read.
However, there was a lot more information that could be even more useful such as a diagram for the External (Engine Compartment) fuse panel as well as better detailed information about all of the fuses, relays, and circuit breakers. This took a while to compile but it was worth it because it will be a handy reference for anyone who could use it.
I created the information in a spreadsheet database and then published it on the internet. From here anyone can reference it any time online. I've also created two pdf document files if you wish to download the information directly to your computer or your smartphone. You can print a hard copy or keep it on your smartphone to access it easily if you ever encounter any issues on the road.
The website and the files both contain detailed information about both the Internal and External Power Distribution Centers, much more than the owner's manual or any other such documentation I could find. For example, you can now very easily find all fuse and relay locations and reference with expanded detail what each one does. Instead of using the esoteric acronyms used in the owner's manual to describe the fuses and relays, I've expanded most of them to their full names. This makes it much easier to understand what each one does.
Please see for yourself. Here is the RAM 1500 5th-Gen Power Distribution Centers website. Also, I've attached the pdf files for both the Internal and External Power Distribution Centers to this post. Simply download them to your computer and/or smartphone. From there you can print out a hard copy if you wish.

The pdf files are attached below. One is for the Internal Fuse Panel, the other is for the External Panel.
I hope you find this information useful.
