Hey guys ive never done this but i have a trex sittng here that i just sold and have been told that it has the lighting coil in it so my 190 can have 12v lighting circuit if i want. My problem is there is only one yellow wire coming out of it and ive been told and all the wiring diagrams on here show ligthing coils had a yellow and a white wire coming form them? Also do i need to switch flywheels or just the stator plate and keep my flywheel? Can post pics if needed but wholesale told me alot of guys have done this swap
