“IGNITION SWITCH”
The most important connection of a wire harness, the ignition switch, will control
power to the switched ignition fuses on the fuse block as well as sending a start signal
to the starter to allow engine operation.
The ignition switch connection consists of wires with section labels reading
“IGNITION SWITCH”. All wires going to the ignition switch can be seen in the Ignition
Switch Schematic below, these wires are:
2 Black/Red: 12 gauge wires, printed [IGNITION SWITCH ] #934 TO IGNITION
SWITCH POWER B+, these wires come from a buss bar on the fuse block and feed
battery power to the ignition switch. These wires will have power at all times.
Black/Orange: 12 gauge wire, printed [IGNITION SWITCH] #933 TO IGNITION
SWITCH "IGN" TERMINAL, this wire provides the switched power source to the fuse
block. This wire powers all of the switched power circuits to the harness, with the
exception of the RADIO/REVERSE fuse. This wire will only have power when the
ignition switch is in the ON/RUN position.
Pink/Black: 16 gauge wire, printed [IGNITION SWITCH ] #931 TO IGNITION SWITCH
(COIL), this wire provides power from the ignition switch to the COIL/FUEL PUMP fuse
on the fuse block. This wire will have power when the ignition switch is in the ON/RUN
position as well as the START position.
Black/Purple: 12 gauge wire, printed [START/CHARGE] STARTER "S" TERMINAL
#919 IGNITION SWITCH "START" [IGNITION SWITCH], this wire will send power to
the starter solenoid and will only have power when the ignition switch is in the START
position.
Black/Brown: 12 gauge wire, printed [IGNITION SWITCH] #932 TO IGNITION
SWITCH ACCESSORY TERMINAL, this wire carries power to the RADIO/REVERSE
fuse on the fuse block. This #932 wire will have power when the ignition is in the
ACCESSORY position and when in the ON/RUN position.
