Gladiator (not JL) Wiring diagram help

[Alc]

I am doing an upgrade on my JTRD to install the front trail cam. With it, I will be installing the CVPM. According to the fuse box diagram the CVPM fuse is F55 (10A fuse). Currently my CVPM is not installed but the fuse is there from the factory.

1. Does anyone know what runs off that populated F55 fuse other than the CVPM?

2. If there truly is a wire coming from that fuse, does anyone know where it terminates?

Thanks in advance for the help!

I’ve scoured the JL stuff already and can’t find any leads for this question.

Battery- pcm- run2 relay in the pcm- f55-(c3-k7pin)- connector xy401 pin 2- mcvp pin 4

It looks like the mcvp is behind the rear seat in the center.

Xy401a appears to be under the pcm near the firewall (59 pin connector)

@Lost1wing First of all, thank you for the help!

Okay, so there is no harness back where the CVPM should be so I assume F55 terminates at the firewall specifically the BCM (Body Control Module) and there should be an empty position on XY401A . So if I am reading this correctly, in layman's terms:

My Interpretation:
Battery -> PCM -> run2 relay in the PCM -> F55 -> into BCM (C3-pin K7) -> out of BCM connector F-XY401A pin 2 -> into [CVPM aka MCVP] pin 4

More Simplified for my application:
F55 -> Enters Cabin and connects into BCM at C3 pin k7 -> exits BCM at F (???) XY401A pin 2 (if CVPM were installed) -> CVPM pin 4

XY401A should be under the pcm near the firewall (59 pin connector) also know as BCM

The picture below is the BCM. From what I can tell visually, all wires enter through the firewall into A, B, C, & D connectors at the top. They are then distributed throughout the interior of the car from E, F, & G (all those alphabetical naming are actually imprinted on the BCM too but is hard to make out in the picture). Now the only 2 connectors that seem to follow to the rear of the vehicle are E & F. Should I assume in the wiring diagram you provided that F (F928) should be the where I should look for the empty connection that would normally go to the CVPM?

@Jimmy07 and @ecidiego do you have any further insight on this since you are the resident experts on this install? Do you happen to know if anything else is run off of F55 because I can't find anything else on the wiring diagrams I've looked at so it appears this is the logical termination point for F55.

I wanted to wire LED sense wires to Xy401a. I was never able to find it and was unwilling to rip the entire dash off to do so.

I found XY401A....it's WAY up there like you said. Do you know if F55 is routed through the BCM at all? None of this makes sense though. Why would there be a huge connector like that to nothing? I mean, it's a fully populated unhooked harness with countless wires. My JTRD is completely loaded with exception to the completed trail cam so what would/could this harness ever lead to?

Bcm layout.
PDC layout.

I don't see the bcm being involved.

Not correct. Basically, the CVPM is the only item using F55. That wire is populated at the fuse box, and terminates at connection xy401 pin 2. You just need to add the wire to the empty pin 2 side of xy401, and run it to CVPM connector pin 4.
The BCM’s involvement is irrelevant. Its job is trigger Run relay 1 when the ignition is switched on. Run relay 1 in turn triggers run relay 2, which switches on F55.

What exactly are you trying to do?

My goal is to use existing F55 fuse/wiring to provide power to the CVPM. I am currently waiting on parts for the rest of the project so I have the time to find alternate ways to power the CVPM.

My preference:
1. release pin #2 from XY401A
2. Route CVPM power to that released pin #2 from XY401A
3. have a very small male-female connector attaching the CVPM power wire to that stock pin #2
Connect a pin to the other side where pin#2 on the XY401A

Challenges:
1. How do you get access to XY401A?
2. What type of pin does it use for that wire?
3. Are there smaller connection boxes that could accept those pins (connection box with 4 preferably 2 pins)?

I assume that the only way to access XY401A is the top down method from the dash. I have had my dash apart before when completing the MOPAR truck-bed outlet but I do not remember seeing or being close to getting to that harness...anyone have any leads to how you can get to it?

@Jimmy07 , @ecidiego , @Lost1wing thank you for steering me in the right direction and helping me understand the wiring diagram!

You have found xy401a and it is inboard and above the bcm? I looked at the pictures for both sides of that harness.

Can you just use a piggyback fuse holder in the f55 position and run a new wire from atop of the PDC and then back to the rear seat area? One just connector to worry about and a lot less work. I see xy401a may be difficult to get to. Hopefully someone else will point an easier way to access xy401a.
