Justin, thanks very much for the reply. I understand completely and that is how I have it wired. The reason you saw the splits on the yellow and green wires coming off switch terminals 7 and 8 are because they cover the corresponding front and rear lights, just like you did. Basically, I've wired the same as you. That leads me to believe there is a problem with the switch or how it is wired. Mine has the fused red going to one side of the flasher. The other side of the flasher has a black wire that goes to one of the middle terminals on the switch. There is a black jumper wire that connects it to the other middle terminal on the switch. Finally, the black wire that is grounded to the vehicle goes to one of the two small gauge wires attached to that little white plastic buzzer(?). After passing thru the buzzer, the wire coming out of the buzzer splits into two red wires that are attached to the two terminals on the opposite end of the switch from the yellow and green. I believe you can see all this in my photo.
Given all that, when I activate the switch toggle in one direction, I get flashing front and rear lights (4 way flashers). When I toggle the other way, I get nothing.
Boy, this is frustrating. Thanks in advance for any suggestions.
