this may be a dumb question but how do the autolamps on gen 3/4's work cause if you cover the black thing on the dash it doesnt make the headlights turn on so where is the dusk sensor? or are there two that work together to judge the level of daylight?

Headlamp Delay System — Autolamp

The autolamp system:

provides light sensitive, automatic on-off control of the exterior lamps normally controlled by the manual headlamp switch .
provides illumination for occupants leaving the vehicle by keeping exterior lamps on for a preselected period of time after the ignition switch is turned OFF.
can be adjusted by the driver to delay exterior lamp shut-off for up to 3 minutes.
The system consists of:

light sensor amplifier (13A018).
autolamp relay (headlamp).
autolamp relay (parking lamps).
an autolamp time delay switch (part of headlamp switch ) which includes an on/off switch.
Connections to the vehicle lamps parallel the regular headlamp switch connections, requiring the headlamp switch be turned to the OFF position for the automatic control feature.

In normal operation:

The system will turn the exterior lamps on when the ambient light available to the light sensor amplifier decreases below a predetermined level.
The lamps will automatically turn off when the ambient light level exceeds a predetermined level during daylight hours.
NOTE: Do not place any items in the RH corner of the windshield which may block light to the light sensor amplifier .



The light sensor amplifier:

is mounted to the instrument panel (04320) beneath the instrument panel upper finish panel (044A90) .
must always be exposed to outside light to function properly.
The autolamp time delay switch is part of the headlamp switch . The autolamp system is functional for automatic operation when the autolamp time delay switch is moved from the off position and the headlamp switch is in the OFF position. The closer the autolamp time delay switch is moved toward the max-delay, the longer the exterior lamps will stay on after the ignition switch is turned OFF.

Yes that black capped dome in the middle of the dash is the sensor for G4s. G3s have a clear plastic sensor that looks like a button (like SHOZ said).

If you've been driving around in the daylight and then you cover the sensor, it takes a few seconds before the headlights kick on.
