Hi.
I have a question about 10570-0705-A021 cable.

It has red wire which is +28V, black wire which is 0, and brown wire.
Red = Pin B
Black = Pin A
Brown = Pin C
Pin D is unused.
Where is the best place in Hmmwv to connect this cable? Red/Black can be connected directly to the battery, but where should the brown wire be connected?
I found information that on brown wire 14V should be supplied when the ignition is turned on, but I am not sure if this information is correct.
