Where is the X117 Junction Box in a 2017 Volvo VNL 780?

[CWGriswold]

I'm new to the forum and have tried numerous ways to search for this info with no luck.

I purchased a used 2017 Volvo VNL 780 and am wiring up some equipment. The wiring diagrams show a Junction Box labeled as "X117 Junction Box (ler)" with 6 separate 12 V DC power feeds and a common ground.

Does anyone know where this is physically located?

Imma guess that's the fuse box under the hood that's also the supply for the trailer?

I don't think so. That is always referred to as the "External Fuse and Relay Center (EFRC)" in the wiring diagrams.

On the wiring diagrams, X117 shows the following circuits:
Fuse F28 - CUST LVD1
Fuse F10 - CUST LVD2
Fuse F87 - CUST BAT1
Fuse F32 - CUST IGN1
Fuse F63 - CUST IGN2
Fuse F23 - CUST IGN3

The corresponding connection designations are as follows
A A & A B
B A & B B
C A & C B
D A & D B
E A & E B
F A & F B

I looked at the main interior fuse panel. The closest thing I could find is the strip on the far, right corner that is used for plugging in the EDL, etc., but the designations are B1-1 through B1-n
