TRUNK RELEASE OUTPUT (Optional Part #775 required)
Locate the trunk release wire coming from the
back of the trunk release switch. You must
determine if your trunk release is a (+) POSITIVE
or a (-) NEGATIVE. (most trunk releases are
(+) positive). TEST for a (+) POSITIVE trunk
release wire, clip your test light to a good
solid ground, probe the trunk release wire with
your test light, press and hold the trunk
release button, if the test light illuminates,
and then goes out when you release the button,
this is a (+) POSITIVE trunk release wire, see
POSITIVE TRUNK RELEASE diagram below for
connections. TEST for a (-) NEGATIVE trunk
release wire with your test light. Clip you
test light to a good solid ground, probe the
trunk release wire with your test light, if
the test light is illuminated, and you press
and hold the trunk release button, and the test
light goes out, now release the trunk button, if the test light is illuminated once again, this
is a (-) NEGATIVE trunk release wire, see NEGATIVE TRUNK RELEASE diagram below for connections.
Connect the WHITE WITH RED STRIPE wire from the 18-pin harness to the WHITE wire of the optional
relay. Please see diagrams for correct connections.
HORN HONK OUTPUT (-)
(Optional part #775)
The existing horn wire will usually be found in the main ignition switch
harness in the steering column. Probe for a wire which will remain
neutral (in some cases may show a (+) positive). When the horn is pressed
this wire will test as a ground or (-) negative. An optional, part #775
will be needed to do this function. Connect the GRAY WITH BLACK STRIPE
wire from the 18-pin harness to the WHITE wire on the optional part #775.
Connect the BLACK wire to (+)12V constant fused at 10 amps. Connect the
BLUE wire to ground, connect the YELLOW to the horn circuit at the
steering column.
INSTALLING STARTER IMMOBILIZER (-) Output (Optional part #773)
Locate the same starter/crank wire located in the main wiring
harness that you have tied the YELLOW WITH BLACK STRIPE wire from
the 4-relay harness into. Cut the starter/crank wire in half,
making sure that the YELLOW WITH BLACK STRIPE wire from the relay
harness stays on the "starter side" and not the "switch side" of
your starter immobilizer circuit. Connect the RED wire from the
starter immobilizer to the "switch side" of the
starter/crank wire then connect the WHITE wire to the "starter
side" of the starter/crank wire. Connect the ORANGE wire from the
starter immobilizer to the ORANGE wire on the 18-pin harness. NOTE:
You will need to cut factory wiring to make an end to end
connection, see "Making Connections".
