The AN/ARC-25 is the USN combination of the AN/ARR-15 and AN/ART-13.

It is briefly described in JANAP 161 at

http://jptronics.org/radios/Military/JANAP161/an.ac/an.arc-25.pdf .

The C-87/ART-13 is listed, but I've never seen any documentation of
its use with the AN/ARR-15.  In later AN/ARC-25 installations, I'm
sure that the C-733A/ARR-15A (standard aircraft control panel)
was used for the AN/ARR-15 and the C-740/ART-13 (standard panel)
was used for the AN/ART-13.  I'd be surprised if a C-744/ARC-5
(standard panel) wasn't usually in the stack, controlling an
R-23/ARC-5 to provide the beacon band coverage that the AN/ARR-15
lacks.

Both the C-733 and the C-744 do not allow mode change of the R-105 and
R-23 receivers.  The C-744 forces VOICE mode, while the C-733 allows
mode selection locally at the receiver.  The C-740 allows VOICE, MCW,
or CW mode selection of the T-47.

It would be interesting to see some actual wiring diagrams of the AN/ARC-25
installation (early and late).  I'm sure that information exists somewhere
but I've never come across it.  That's surprising, because the AN/ARC-25
appears to have been a very commonly used system (often with two AN/ARR-15s)
in USN aircraft before the AN/ARC-38 began replacing it in the mid- to late-
1950s.
