Was on here many moons ago until I put all the toys in a storage container and moved to TX for a while. Sleds and ATV sat for 5 years, they came out about a year ago when I got home to WI and the 650 wouldn’t go into 4wd, tested everything, tried the repairs and actuator was cooked. So locked it in 4wd and that’s how it’s been until now. Hunted for the 4 wire unit and apparently its been discontinued per AC so found a 3 wire unit in stock. Does anyone know if the 3 wire can be installed where a 4 wire was? I have 950 miles on it and would like to get everything 100% again. I have no issues soldering and splicing wires to make it happen just don’t know what to do with the other white/red tracer.
