Brief Description:  Wiring up the fuel sending units

I opted for the capacitence fuel probes so my AFS EMS system comes with princeton fuel sending units to convert the signal from the tank to something the EMS can display. Each tank has a box and they need their own ground, power and signal wires.
Today I wired them up. Ground was connected to the AFS chasis ground - it was convenient.
-Power had to be established as I didn't realize they need their own power. I used one of the spar C/B (3 amp) that I had in the c/b power. I had to get power to the C/B and then to the boxes
-Then I soldered in a 1.5K resistor in line with the signal wire per the instructions and wired them up to the EMS harness.
Done
