NOTE: When testing the door pin wire, make sure
the dome light is on. Some vehicles, if the door
is left open for a period of time, the dome
light will go out, resulting in a false reading.
DOME LIGHT (Optional Part #775 required)
To determine if your dome light is turned on
with (+) positive or (-) negative trigger,
probe for a wire in the driver’s side kick
panel that switches polarity when the door
is closed then opened. You can also find this
wire going to the under dash courtesy lights.
•If this wire reads +12V when the door is
open and (-) ground when the door is closed,
it is (+) positive. (most Fords)
•If this wire reads (-) ground when the door
is open and +12V when the door is closed, it
is (-) negative.

TRUNK RELEASE OUTPUT (Optional Part #775
required)
Locate the trunk release wire coming from
the back of the trunk release switch. To
determine if your trunk release is tripped
by a (+) positive or a (-) negative (most
trunk release switches are (+) positive).
Place one end of your test light to ground,
probe the wire. Press the “Trunk” button,
if the test light illuminates, you have a
(+) positive trunk release. If it does not,
connect the test light to +12V constant
and probe the wire. If the test light
illuminates when the button is pressed,
then you have a (-) negative trunk release.
Connect the WHITE WITH RED STRIPE wire to
the WHITE wire of the optional relay.
Please use figures below for correct
connections.
