1974 Scamp #2

Been cleaning up the wiring harness for the engine and got a wire with a few plugs on it I dont know what they go to. It dead ends into some kind of relay. Not sure what its for being I didn't take the car apart. If you follow it back from the relay there are two plugs and maybe a ground. Anyone, anyone ????

Here is a pic from the 74 FSM that shows what that is.

Were you able to get the fender top blinkers wired?
