NOT OEM 3-Wire replacement horn for 1999 Saturn SL1,
If you want a challenge, the plastic connector housing on the original 3-wire horn contains a circuit (sealed in the green material) that still should function. This circuit can be removed without damage by using a 1/4″ drill to drill about 1/8″ down to disconnect the 3 plastic rivets that hold the circuit board to the horn. With the circuit assembly removed from the horn your attachment options are endless. I suggest that you attach short wires from the circuit board assembly to the replacement horn, since you may need to replace that horn in the future.
With the connector disconnected from the old horn, test the leads with a meter or small test light to see if it responds to the horn button being pressed and the remote lock. Now test the horn to see if it will work. If it does, the problem will more than likely continue to be intermitten due to oxide build up over time on the contacts inside the horn. Replace the horn with a cheaper model than this one (I found several before I mistakenly bought this one), since there is no point to pay up for an aftermarket OEM horn that does not exist.
Just an FYI, the horn is actually powered by a NPN BUZ11 transistor. This is contrary to most who incorrectly think that a relay is required to switch power to the horn. In fact, the horn has similar functioning as a relay except when the coil is actuated it resonates a small metal dowel that is connected to a thin metal disk to make the horn sound. Have fun.
