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.
