What is the difference between F1+,F2+ and F1,F2?
When soldering an LED to F1-F4 can the positive and negative (anode,cathode) be soldered on to the F1-F4 outputs?
Why are there two F0F+ and not two F0R+?
Does the DH165A0 and other Digitrax decoders have two pairs of motor outputs one on the bottom of the DH165A0 and another on the top and another on the bottom.

Why are there two F0F+ and not two F0R+
Because lighting effects (i.e. Mars lights, ditch lights, strobes, etc.) happen on the [F]ront end of the locomotive rather than the [R]ear.
As per pg. 2 of the manual, the DH165A0 is a plug 'n plug decoder for the Atlas U33 locomotive. The motor wires (red and black in the photo) conveniently attach to the side motor tabs. The additional or redundant motor vias are most likely for installation in other locomotives where the motor wires are on opposite sides of the board.

Time...It marches on...without ever turning around to see if anyone is even keeping in step.
It's in the instruction sheet. One set of commons has current limiting on it, the other is full voltage. The extra F0F set of connectiosn is because the older Kato built Atlas locos came with just a single light bulb in the middle of the loco over the motor. So unless you cut back the light guides and connect an individual light to the F0F and F0R, the center contacts exist to solder on the stock light bulb.
