30 to pos. battery +
(series fused)
also to switch side 1,
opposite side of light
emitting diode.
86 to ground negative
battery.
87 to LED Light
(+ Red wire).
LED other lead to grd.
(black Wire)
87a not used.
85 and 86 relay coils.
30 and 87 contacts.
Three Lug Switch
Center lug goes to relay
(85)
Side one goes to + Battery
(fused).
Side two goes to ground,
either under dash or
wire back to - Neg.battery.
Test center lug to each side
with an ohm meter, the
side which shows a resistance
is the led light emitting
diode side and this side
goes to ground (- battery).
Place the LED light
where there is air
circulation around the
unit to keep it cool.
Neatly run all wires and
secure in place.
Keep all connections
weather proof to prevent
corrosion.
Keep in mind that if LED
is placed in front of the
radiator this may hinder
airflow and reduce cooling
to the radiator.
