[Milsurplus] GRY106 connections

[W Private]

I recently acquired a GRY106 radio and amp.
I have the manual.
I do have the dogbone.
I have a hernia from moving it.
Does anyone have a pin out for the four pin power plug?
I think I have it, but would like confirmation before I plug it in.
I do have a pretty big 24V supply.
Also I could use the pin out of the ten pin audio plugs.
I can't seem to find this. I guess I could figure this out without hurting anything if I get it to power on.
I think the mic is 50 ohms, what is the speaker? Any advice on both of these?
I do not have a handset or mic or speaker, I think I would like to acquire some of these if I get it running..
I think I would like to have the whip antenna once the radio is working.
I have the sides but not the bottom of the base.
I have lots of wire and connections that I may be willing to part with if someone needs some.
The unit supposedly was working when it was purchased from the national guard, along with the communications truck it was in, so I got lots of the connectors that were cut out of the truck.
Thanks in advance for any help that you may be able to give.
I hope to join the group on the net. 
Thanks, Wally KC9INK
