Ammeter hook up and bonus question

I got my trailer completely disassembled, and slowly getting things pieced back together..

The ammo-meter on the control panel has one black and one red wires.
The wiring diagram in the service manual says that they hook into the 12v distribution panel. Where on the 12v distribution panel.

Bonus question:
The tank sensors have like 5 wires or something. A red and some others. The wiring diagram shows the other 4 (not the red) all coming together into one wire so that two wires go to the control panel for each tank, a red and the "combination" wire. Is it that simple or is there some other piece(s) to it?

Thanks in advance.

The wires for the amp meter connect to a shunt on the 12 volt panel. It is a flat plate with two wire connections. Mine does not work very well, it is on my list of things to check out some day.

In the tanks there are 4 probe sensors and each has a resistor connected to it. There is also a probe that is connected to the switch for each tank and feeds 12 volts into the tank. The fluids in the tank complete the circuit from the 12 volt (switched) probe to the probes that are covered. As the tank fills there is less resistance in the circuit and the meter moves accordingly.

So the resistors are built in to the probes? So the place that I hook the wires into the probe should be it, then I can splice the wires together there?

I'm going to guess that the shunt for the ammeter is something extra that is not on the 112v panel out of the box..

Thanks.

Here are a couple of pictures that might help. One is the 12 volt panel in my trailer. It shows the red and black wires and how they attach to the shunt on the board.

The other is wire diagram for my 75 that shows the wires from the tanks to the panel. Hope these help.

Ammeter, etc etc.

Daniel B, I hope you do not mind me hooking in here with related questions.....
I am replacing the old fuse panel and Univolt with a PD 4045 combined unit. My old panel looks exactly like azflycaster's.

Can anyone tell me where on the new panel I should connect:
1. car battery charge line (blue)
2. power-on wire (grey)
3. ammeter wires (black, red)?

Thanks in advance.
