Wiring on BigTex Dump Trailer?

[NIdaho]

Coming into the Battery/Pump box on the tongue are 3 wires.

• White
• Red/Orange
• Blue

Am I correct to assume that the

WHITE is Ground and should be attached to the negative terminal of the trailer battery

BLUE is the power to the Break-away Switch and should be connected to the "+" terminal of the trailer battery

RED/ORANGE This line is RED and then has a section of Heat Shrink with some sort of cylinder under the Heat shrink and then is ORANGE with an in-line 30 Amp fuse. I think this might be the +12 V (battery charge line) coming from the plug

Should the RED/ORANGE be connected to battery's "+" terminal as well or should there be some sort of Battery Charger/Isolator?

Thanks,

Bob
