My B7100 has a pair of wires with round style connectors coming from the wiring harness, right above the brake pedal. (red arrow, pic below)
Definitely factory.
Wires are too faded to see what color they were, unless I open up the harness wrap near them.
Anybody have any idea what they were used for?

I'm pretty certain my old B7100 had the same connectors there, but everything worked so I didn't create myself a problem by trying to figure out what they were for.

Actually, it had brake lights, but they didn't work. Maybe those connectors are for a brake switch?

That sounds feasible, I didn't realize any of these had brake lights.

I think I have seen those on my B7100 as well. I will look again tomorrow when I use it.

Might be worth hooking the wires to a meter to see if they are hot under different conditions. Like mentioned, might be wires for some brake lights.

I read somewhere that they were for a cigarette lighter but I can't remember now where I found it. I was looking for brake light connections or a way to install brake lights when I came across it.

Optional front flasher lamps?
Horn?

EDIT: Looking over further, it's most likely horn.

Except mine has the factory horn & switch ( that still work) in addition to these wires.
Tomorrow I'll test to see if it's hot when the headlight switch is on.

Does your B7100 have 4 way flashers or turn signals?

No, so that is a definite possibility.

I found that niether wire is grounded, regardless of ignition key on or off, or light switch on or off.
Niether wire is hot, regardless of ignition key on or off, or light switch on or off.
So I'm convinced that these wires were for emergency flashers or turn signals.

Would make since, because when you don't have it they leave out the wiring under the dash for it. ;)

I have a european version of the B7100 and where those wires come out of the loom is the same place the wiring for the rear of the tractor come out of the loom on mine.
