Anyone know what this wire is for? It was tied up behind the left side of the front bumper. As far as I can tell everything works, so I'm wondering if it's unused from the factory. The wires are black (ground) and white with a red stripe. Car is an '86 N/A GL.

 

looking at the marker light diagram, not too many 2 wire plugs. Can you tell me the colors, looks like one is solid black, the other I cannot make out.

 

One wire is black, and the other is white with a red stripe.

 

Most likely it is for the headlamp washer, which is an option you don't have. EL 199 shows the engine bay wiring harness, it is a round profile plug like you showed, on connectors, its very helpful to get a picture looking into the connector, showing the pin out side and plug interface shape, since the diagrams usually have a 3d view and a mechanical schematic view. I haven't verified color yet, as I haven't found it on the wiring diagram, which is way fun to peruse.

 

Black wire & Gray wire with a red stripe is the washer motor, colors could have faded a bit, about 95% sure on this one !

 

Thanks! That looks like it. I tried looking at the schematic, but not knowing what system to look at made it a bit difficult.
