[Milsurplus] Recognize these connectors?

[Hue Miller]

#1 -  4 pin ARC-12 type connector - what does it connect to?

#2 - Monowatt labelled connector - pins marked A thru M
in this pattern ( i gotta try this, even tho many email programs
will rearrange the spacing )
                    A   B
                 C        L
              E     M      K
               G             J
                      H

E,K,G,J are big pins.    Marked  "28 Monowatt 188-1".

Tnx, Hue Miller
