However
the horn can easily be wired using the included 12 Volt 30 Amp Relay (b) and some basic
electrical supplies.
Step One:
Connect terminal 85 to the OEM horn harness negative (-) wire.
Step Two:
Connect terminal 30 to the OEM horn harness positive (+) wire. Install a
fuse holder in-line.
Step Three:
Connect terminal 87 to the positive terminal of the Compressor.
Step Four:
Connect a ground wire from the negative (-) terminal of the Compressor to
a ground point on the vehicle or the negative terminal of the battery. Looking at the
front of the horn the negative terminal will be on the left.
Step Five:
Connect Terminal 86 to the OEM horn harness positive (+) wire.
Step Six:
Install a 30 Amp fuse into the fuse holder.
Note:
Place the Relay in an easily accessible location for convenient service in the event
of a faulty relay.
