I am sure this is an easy one for most of you. I am finishing up wiring my 39 knucklehead and for some reason I can't find where the wire soldered on the speedo light switch goes. Also, I have the headlight, taillight and the two dash electric/oil lights working but I cannot get the front fender lamp to stop shorting out the system. Any info you can provide to help me out is appreciated. Here are a couple photos.
