This..This is the WIRING GUIDE for my rec/rec.>>> http://gallery.trailtech.net/media/instructions/lights/regrec/010-ELV-116.pdf. I wired mine up the second way!
.all the directions i've seen for adding a reg/rec call for no frame grounds,
attach the ground from the stator directly to the one side of the reg/rec, the other gets the positive(hot) lead, the 2 output leads of the reg/rec directly to the battery.
then all accessories get a dedicated ground connected straight to the negative of the battery also.
no frame grounds.
.
Ground from stator (blk wire)and yel/red goes to yellow wire to reg?, and all other ground arr the same? But i have a wirewht/ green, and i dont know where it go connected I have this stator

that stator will work for either the 4 or 5 wire harnesses
if you have a 88-02 4 wire harness, the extra green gets grounded to the frame.
on the 03+ models that green wire goes into the 5 wire harness and to the CDI,
it is for the ignition, and has nothing to do with the lighting coil.
thats what the loose green wire with the round eyelet on is for in the ebay ad you posted above, connect it to the extra green wire and put the eyelet under the bolt with the other ground at the coil
