You need 4 diodes , the ones that have 2 ins and 1 out , can find them at your RV store , cut hot wire going to the lite , splice them into each lite , the out side facing the lite , the front lites have tobe spliced in the fairing , the rear can be splice under the seat , run a wire to each of the diodes, plug wire into the left over in side of the diode , run all 4 wires to a switch, other side of switch to a 2 prog flasher can, than to hot fuse . give me a few mins. and I'll down load a wiring diagram . because after reading this , it is as clear as mud .
