I have a CX-75/TRC-2 power cable, the 50 foot  cable from the G-50A to the TRC-2 radios, either BC-1306 or TRC-2.

Contacts 55, 58 on the plugs are not carried thru, are open.

Can this cable be used with GRC-9 and gas engine gen ?

I do not know at present what pins 55, 58 do, but if i have to, i will study the manuals and learn it.

thanks-
