KEYLESS ENTRY AND APPROACH LIGHTING
A keyless entry system offers quick and convenient means of locking and unlocking the car doors.
It has become so popular that it’s standard equipment on virtually every new car being sold. Although
keyless entry equipment is not included with this kit, the Power Center has been designed to connect to
commonly available systems. Wiring details can be downloaded and printed from our website:
When properly connected, the Coach-1 Power Center will control vehicle lighting in response to
the door lock and unlock signals generated by the keyless entry system. At night, when a door unlock
signal is received, the Power Center will activate headlights, signal lights, and dome lighting to illuminate
the area around the car as well as the interior as you approach the vehicle. These lights will be
automatically turned off in approximately 30 seconds unless a door is opened, but can be reactivated by
another door unlock signal. In daylight, the approach lighting will not be activated but the signal lights
will flash to let you know the unlock signal was received.
When locking the doors, day or night, the signal lamps are flashed to indicate the signal was
received. However, in bright daylight it may be difficult to see the lamps flash, so if you press the lock
button on the key fob a second time, the horn will chirp in addition to flashing the signal lights.

MOUNTING AND GROUNDING
The Coach-1 kit includes a light sensor cable assembly used for the automatic headlights. This
cable assembly has been specially calibrated and any modifications will void the warranty on the cable.
The sensor should be mounted in the center of the dash, close to the windshield for maximum daylight. Be
sure there is enough room under the dash for the sensor and cable and that the cable will reach the sensor
connector on the Power Center. In the center of the dash drill a 0.257 inch hole (ANSI drill size F, or
metric 6.5mm) for a snug fit. Install the sensor retainer from the top of the dash. Slide the clamp ring over
the sensor onto the cable, then insert the sensor into the bottom of the retainer underneath the dash. To
hold the sensor in place, slide the clamp ring up and press it firmly around the sensor retainer until it’s
flush with the bottom of the dash.
