4 battery set up

[Mmiller412]

I’m trying to run a 4 battery set up in my m923. The diagram under the seat shows how to do it. But I t shows there’s a third wire coming up from under the battery box in the center thru the floor. I do not have this wire. Anyone have the same issue or know what to do?

If you are talking about the smaller wire, that is for the 12v side of the heater motor. Should be wire #569 I think.

No it’s not that. I’ll post a picture of the diagram in a bit. It’s three 2 gauge wires coming up from the floor. It’s not one of those tiny 16 or 18 ga ones

Hmm. I wonder if it's the cable for the NATO jumper cable.?
