Can't find out what these are used for, searched my Haynes manual's wiring diagrams, searched google images, and random forums with no luck. Maybe someone on here can shed some light on it. 1983 RX7
Image #1: These are the wires in question a solid blue and solid yellow wire coming from the firewall on passenger side
Image #2: harness connected to it, leads to a relay and a 2 prong connector also a single solid black wire w/ male snap plug terminal. (obscured by shop jacket)
