Some have removed the board in the cradle and worked in my case it did not and had to change the harness. If you remove the right front headlight you can see where the harness runs down the side of the frame then to the right side of the Spyder.
My harness goes into the frame. Don't see where it comes out. Apparently there's folks want a 660 harness and zumo so I'm going to try and save it if it doesn't work. The antenna end of the harness is by the tank isn't it? Thanks
