AUXILIARY SWITCHES (IF
EQUIPPED)
For maximum vehicle performance, keepthe following information in mind whenadding accessories or equipment to yourvehicle:
•When adding accessories, equipment,passengers and luggage to yourvehicle, do not exceed the total weightcapacity of the vehicle or of the frontor rear axle (GVWR or GAWR asindicated on the Safety ComplianceCertification label). Ask an authorizeddealer for specific weight information.
•The Federal CommunicationsCommission (FCC) and CanadianRadio TelecommunicationsCommission (CRTC) regulate the useof mobile communications systemsequipped with radio transmitters, forexample, two-way radios, telephonesand theft alarms. Any such equipmentinstalled in your vehicle should complywith Federal CommunicationsCommission (FCC) and CanadianRadio TelecommunicationsCommission (CRTC) regulations, andshould be installed by an authorizeddealer.
•An authorized dealer needs to installmobile communications systems.Improper installation may harm theoperation of your vehicle, particularlyif the manufacturer did not design themobile communication systemspecifically for automotive use.
•If you or an authorized Ford dealer addany non-Ford electrical or electronicaccessories or components to yourvehicle, you may adversely affectbattery performance and durability. Inaddition, you may also adversely affectthe performance of other electricalsystems in the vehicle.
The auxiliary switch option packageprovides four switches, mounted in thecenter of the instrument panel. Theseswitches operate when the ignition is onor from battery power, depending on theswitchable power distribution box fuselocations #82 and #83. We recommend,however, that the engine remain runningto maintain battery charge when using theauxiliary switches for extended periods oftime or higher current draws.
Note:When your vehicle has a dieselengine, use the auxiliary switches only whilethe engine is running. The glow plugs alsodrain battery power when the ignition key isin the on position. Using the auxiliaryswitches, even for limited amounts of time,can cause your battery to drain quickly andprevent your vehicle from restarting.
When switched on, the auxiliary switchesprovide 20 amps or 40 amps of electricalbattery power for a variety of personal orcommercial uses.
The relays for the auxiliary switches are inthe power distribution box under the hoodby the right-hand fender. See yourauthorized dealer for service.
Each switch includes a power lead, ablunt-cut and sealed wire below theinstrument panel and to the left of thesteering column in the driver footwell area.
The power leads are coded as shown:
