ray. the original  grc106 install instructions 
called for all cables hardwired to the batt terminals.  later on the standoff terminal kit for the 151 was developed probably to make it easier to disconnect or replace batteries. all the other install kits for different vehicles called for hardwiring right to the batt post.  the only vehicles that had dc overcurrentptotection of radio power cables was on the armored vehicles using the mx7777 combination breaker and transient suppressor

Also plan on running external 28 volt MEP-015 and bring that in via the slave connector so I can run everything on board without having to run the engine.
> Got the slave connector installed, terminated the cables on that end along with all the clamps for the huge cables that run back to the battery compartment along with all the new power cables that will terminate in the battery compartment and am now looking at five cables that want to terminate in the battery compartment. Two zero gauge power cables, one for the mutt electrical system and the other for the slave connector, two #8 coaxial cables that power the GRC-106 and one power cable that feeds the VRC-12. The next trick will be connecting everything up to the batteries and the auxiliary power stud kit that’s feed from a jumper with a 60 amp fuse from the batter terminal. Things are getting tight in that space, anyone have pictures of what the mill spec installation is? I have documentation on the VRC-12 and GRC-106 installation on the M151 but nothing on what is supposed to be in the battery compartment.
