You don't need a "one" wire. A three wire only has two wires to route. One wire more than one wire. The so called three wires are: the battery cable on the alternator power stud, the sense jumper (alternator blade 2) and the exciter wire to Ignition switch. (alternator blade 1)
CLICKHere is a list of "advantages" of "one wire" from a supplier. See anything that is not snake oil?
Simple installation.... OK good, both use same bracket and bolts, wiring no factor
Single wire installation....covered that
Built-in voltage regulator...... both do
Eliminates excess wiring.....excess?
Low RPM turn on and charge........wrong
Fits factory applications.....both do
Low and high current applications......both do
Multiple finishes available..........both do
ONE WIRE NORMALLY MORE EXPENSIVE.
