Question about 1996 Saturn SL
Can I just slice the wires and connect the two grounds together and use that alone connection, and use the power wire as the other connection
I am not an expert on auto horns, but can solve most electrical problems. Do you have a multimeter? Using the ohm-meter, measure the ohm value between the two wires, and from each wire to the horn mounting bracket (you need contact with un-painted metal. The value between the wires should be low (10-100 ohms) but not zero. This represents the horn coil. The value between each wire and the bracket should be very high (10 kilohms or more). This means the horn coil is not grounded to the bracket.
Now, using the voltmeter, measure the voltage between each wire (from one wire to another). The value should be zero before pressing the horn button, and 12 vdc when the horn button is pressed. I would expect one of the wires will also be zero ohms (ohmmeter) when measured to the car frame or body.
Ok, you are ready to hook up the horn. The auto ground wire(s) are connected to a horn wire that is common with the horn bracket. Or, connected to a black horn wire if both horn wires are isolated from the bracket. Connect the auto switch wire (the one that reads 12 vdc when the horn button is pressed) to the remaining horn wire.
