External PDC 10 amp red, internal PDC 15 amp blue...
Thanks - I'm learning a lot! I just purchased a Switch Pros controller whose instructions state that in order to control the Switch Pros panel backlighting, one needs to tap into side marker lights / headlights. The only fuse I see is the 40A MCASE+ at F07. How do you use a fuse tap for this type of fuse - do manufacturers make such a tap - or should I look for an alternative method?Spare Fuses:
Since RAM uses so many different types of fuses, it's difficult and costly to purchase spares for the road. The biggest problem is finding MCASE+ slotted fuses because these are rare.
With some searching, I was able to find a selection of fuses for each category that can be purchased for spares.
MCASE Unslotted and MCASE+ slotted:
These were the hardest to find, especially the MCASE+ slotted, but this handy kit contains both:

These aren't as difficult to find. This kit contains enough of a selection to cover the RAM's needs plus you get three taps as a bonus which will come in handy if you ever install add-on accessories.

These are a bit hard to find but this kit has all that you'll need:

Also, keep in mind that RAM includes some spare fuses in the External Fuse Panel. I'm not sure if these are the same for all 1500s, but here is a list of the spares that came with my truck:
Micro2:
Micro3:
- 5 Amp
- 10 Amp
- 20 Amp
- 25 Amp
MCASE Unslotted:
- None
MCASE+ Slotted:
- 20 Amp
- 30 Amp
While this is a decent selection, it does not cover all of the fuses in the RAM 1500. Missing are:
- 40 Amp
- 50 Amp
Micro2:
Micro3:
- 15 Amp
- 25 Amp
MCASE+ Slotted:
- 10 Amp
- 15 Amp
If you want to save money purchasing spare fuses, then just concentrate on these.

Where did you end up tapping to for your Switch Pros panel?Nevermind! I see my answer in another post!
They are according to the schematic and circuit description.Are the lamps being powered by the BCM directly?
I use Alldatadiy.@HAL9001 or anyone having an idea,
is there a source to get the full wiring diagram, (vin/model/year specific) for the truck from? Maybe some RAM technician website with a yearly/monthly fee?
Just use the listing as a general information, then use a test light to confirm. The post is no longer accurate. I was responding with another member the other day, when he asked about power for rear USBs. I looked at this posting for the answer. This post had a circuit breaker #5 listed, but no picture of one. There is no circuit breaker #5. I looked in my 23 manual, and there are a few differences. This is a good reference to start with, but your proper list is in your manual. Even if you lost yours, it's available on Ram's website, or app.Question: is the external F44 (trailer camera) an ignition-on fuse? Or does it only get power when a camera is installed? Thinking of using that for my TRX grille lights.
Well my truck is barely two months I sure hope I haven’t lost itJust use the listing as a general information, then use a test light to confirm. The post is no longer accurate.
