There is a thread in the Archives for Battery Forum where I converted an F3 to RC  for use with a trail car. There are lots of pictures.
and explanation.

2 different boards !! went to the site & found the one for GP38,not same as GP 30


Does the GP-30 have two plugs coming off each motor block?
 
Does one of these plugs have two red wires and two black wires coming from the motor block?
 
Are these plugs connected to the power distribution board on the floor of the GP-30?

Paul,

 The USA engines I have have two plugs coming from the motor block. The plug with four wires going to it are for the track pickups.  Unplug that plug, and plug in another plug if you have them ( going to the board).  You should have plug on each end, one for each motor. Once you do that you should have four wires two red and two black.  Make sure the wires are connected right so the motors run the same way. Wire your battery plug to them. Everything should work just like track power, smoke, lights. Hope this helps.

Don

yes-yes & yes

Mike, based on your answers the GP-30 is wired the same as the GP38-2 and every other USAT four-axle diesel.
 
Follow the GP38-2 example on our club web site and you will have no problem installing an MU plug.
 
Unless you intend to MU your GP-30 with other diesels, there is no need for an MU plug on the front. Why spoil that pretty face! An MU plug on the back will power both motors as they are connected through the power distribution board.
 
Let me know how it turns out.
