What is this connector supposed to attach to?
 

Hello all. I have a mysterious connector in the engine bay of my car and I'm hoping someone can tell me what it should be connected to. It is located right below the ignition coil. It has three wires; Red/White-Stripe, Black/Yellow-Stripe,Red/Black-Stripe. I thought it was for the engine compartment light but I believe that connector is to the right of the air filter. I've attached a picture of the connector. Thanks for your help!!

Usually, that connector shape goes to the oxygen sensor. I don't have my wiring diagram at home to verify the wire colors.

Oxygen sensor was my first guess as well. But the Oxygen sensor connects to a connector underneath the fuel filter. The yellow arrows point to the connector from the oxygen sensor

It's a test connector.

On CIS cars you can use 2 of the ports with a Dwell meter to set the CO on the car.

I just looked my 84 does not have that connector

Rear window defroster. Blk/yel feeds the third brake light. Final answer.

Rear window wiper - I recently disconnected mine when I removed the whale tail

Definitely final answer. Just been working on this in my car ('88).

For the targa the Rear Defrost in the wiring diagram shows Red/Blk and Red/Wht with no wire for the brake light. The rear wiper is shown as having Red, Brn/Blk, Red/Black which seems closer. The blk yellow is throwing me off. I will check tonight when I'm working on the car. Thanks for all the feedback!
