    Post Looking for Information on Relay / Circuit Breaker

    I need help figuring out exactly what this is for and where I would be able to find another one.
    I have a 1980 Mustang Cobra that originally had the turbocharged 4 cylinder and was swapped with a 302 from a 1974 Ranchero as far as I can tell the wiring harness for the engine was also taken from the Ranchero.

    First: Welcome to the forum!


    Fwiw, I massively suggest:

    Ebay search: 1974 ranchero service manual


    https://www.ebay.com/sch/i.html?_fro..._BIN=1&_sop=15
    Ebay search: 1980 mustang service manual


    Isn't your car worth the "super expensive" ~~$100, in order to have the proper service manuals?
    Compare that cost to your typical overly expensive monthly cell phone and cable bills. Are those more valuable than the one-time-purchase for having the correct manuals for your car? :-)


    If you have questions after you get the manuals, then post pictures of the schematics, car engine bay, overall wiring, and ask.


    Good Luck!

    If you have questions after you get the manuals, just ask. Hopefully, someone can help.
    The engine electrical wiring of a 1974 Ranchero shouldn't be too complicated.

    Good Luck!

    I will say that i picked up a complete set of 1984 factory manuals and they have already paid for themselves.

    Its clearly not from the 74 Ranchero, the part number is a 1980 series so probably original to the car.
