Anyone have any info on the wiring for an air horn for a 97' SL2. I'm replacing the broken horn on my SL2 with an air horn. The car already has 3 existing wires, I assume one is gnd, positive, and relay/switch? Just wondered if anyone has installed another type of horn on the saturn. Thanks, I posted a message earlier but it never showed up.
I just installed a set in my 99 SW2. The three wires to the stock horn are
1) constant power 2) switched ground 3) constant ground I did not hear any relay click when I disconnected the stock horn, so there may be a relay in the old horn itself. In any case, you should wire in a relay. I tapped a power line for the air horn compressor from the fuse box next to the battery-I used a mini fuse relay and a connected it to the bolt connecting the battery cable to the fuse box. Then, I ran power from the fuse to the relay to the compressor. I grounded the compressor. Then, I hooked the switched ground and constant hot from the old horn wires to the relay.Lee
A Haynes or Chilton manual from any auto parts store (for around $10) will provide vehicle wiring diagrams.
