How to Add a Backup Alarm
Beep, beep, beep. You've heard the sound as you approached a work
site. The heavy equipment and big trucks sound an audible alarm
each time they are driven in reverse gear. It makes sense to warn
other workers, since the operator of the equipment doesn't have the
same field of view as he would moving forward. If you have
equipment that is required to have a back-up alarm or think it
would be a good idea to equip your truck with one, even though not
legally mandated, adding a reverse-gear alarm is a job you probably
can handle yourself.
Step 1
Set the emergency brake on your vehicle.
Step 2
Turn the ignition key on your vehicle to run, but do not start the
vehicle's engine.
Step 3
Move the shift lever to reverse to turn-on your vehicle's back-up
lights.
Step 4
Connect the ground wire of the 12-volt test light to a bare metal
part of the vehicle's frame, bumper or sheet metal.
Step 5
Penetrate the insulation of the wires leading to the vehicle's rear
tail light assembly, one at a time, until you locate the one that
turns on the test light. This is the wire that feeds the back-up
light.
Step 6
Locate a position on the chassis of your vehicle to mount the
back-up alarm. The exact location will depend on the model and size
of the back-up alarm you choose and the model of your vehicle. The
location should be toward the rear of the vehicle, shielded as much
as possible from road hazards and in a spot you can access with the
tools needed to attach the alarm to the chassis. Mount the alarm to
your vehicle.
Step 7
Connect the negative or ground wire of the alarm securely to one of
the studs bolting the alarm to your vehicle.
Step 8
Connect the positive wire of the alarm to the wire you identified
as the back-up light feed using a Scotch-Lock solderless connector.
If the positive wire of the alarm is too short to reach the back-up
light wire, lengthen the positive wire with a length of 16-gauge,
copper automotive wire, connected with a solderless butt connector.
Support the wires firmly against the frame or chassis of the
vehicle with nylon wire tie
