1. Locate a suitable site to mount the unit, usually the firewall or the hood is a good option. The location must be a flat metal surface where the magnetic mount will hold best. The firewall or the hood works best on most vehicles because the unit front side will be directed into the engine compartment. If mounting on the hood, the best location is near the rear of the engine compartment, that is the location where most pack rat nests are found. Also, pick the location where there is no shadow cast on the area you are trying to protect and there will be no interference with the body as the hood is closed.

2. Once a suitable location is found, clean the area, then simply place the unit there.

 3. If you have a top terminal battery, attach the red alligator clip to a convenient location on the positive terminal of the battery, usually the clamping bolt.


4. The Alligator clips will work equally well with the side terminal battery, usually it will clip directly on to the hex head bolt. Or, if you have an after  market terminal, it will clip on to the wire side of the terminal.

5. Clip the alligator clip with the black wire to any convenient ground, such as the battery, or any other location that is a solid ground point. Please note that for clarity the alligator clips are shown without the insulating boots.  Do not remove the boots, they are there as a safety precaution.

6. Using the supplied plastic ties, secure the cable and any excess cable to an existing wire harness or other suitable location. Be careful to route the wires away from the exhaust manifold or other hot locations in the engine compartment, and check to make sure that the cable won't be pinched as the hood is closed.

7. Check to insure that the unit is blinking at a 1 to 2 second rate.  If not blinking, check the power connections.

8. To further discourage pack rat nesting, as a final but very important step, clean out any nests or debris in the engine compartment. Wear rubber gloves and a face mask when doing this to avoid possible exposure to Hantavirus

9. Close the hood and check to make sure that there is no interference between the unit and the vehicle body or any other engine components

You're done!

To  further discourage pack rat nesting, here are a few tips:

    Park away from densely vegetated areas where pack rats may have their middens or nests.
    Clear out any areas around the home that would encourage pack rats to nest.
    Trim bushes and cacti up off the ground.
    If you park in a carport, clear out any debris or stored material where pack rats might want to hide or nest.
    In cases of severe infestation, it may be necessary to use a live trap such as a Havahart (C) trap and remove them to another location, or humanely euthanize them.

In some cases battery corrosion or dirt
may cause difficulties in opening the
battery compartment of the the RC-4.
If you have this problem, use a knife
or small blade screwdriver to help
open the battery compartment
