Thanks All.
I was able to pull up the electrical battery schematic and found the only device is an Isolator Solenoid between the Chassis battery and the house batteries. That said I am going with the OEM pin #4 to the 7 pin connector and attach it with the Demco kit I bought for the Ranger. At least I will have the diode to protect whatever.
