Before any Hot Wiring attempts:
Test and record the way each wire tests in the following positions:
With the pedal up:
test the wire with the Ignition Key in the
OFF
position
test the wire with the Key in the
IGNITION ON (RUN)
position
test the wire with the Key in the
START
position
With the pedal down:
test the wire with the Ignition Key in the
OFF
position
test the wire with the Key in the
IGNITION ON (RUN)
position
test the wire with the Key in the
START
position
With this information for every wire at the switch, determining what type of clutch
switching system you have will be easy.
Direct Feed:
The simplest type of system to test and bypass is the “Direct Feed” system. This circuit
simply interrupts the +12 V signal starter wire from the Ignition switch to the starter
solenoid. There are 2 wires in this circuit, the “key side” wire which goes from the clutch
pedal to the Ignition switch, and the “solenoid side” which goes from the clutch switch to
the starter motor. When the key is turned to the
START
position without pressing the pedal,
you will test 12 V only on one of the wires at the clutch switch, this is the key side. When
the pedal is pressed down, and the key is the crank position, the other wire will now also
read 12 V, this is the solenoid side wire. To confirm you have a direct feed clutch switch,
hot wire the “solenoid side” wire with fused +12 V, and the starter motor will crank.
Connect the starter output from the Remote Car Starter to the Solenoid side of the wire.
Note:
In the next two systems a Relay in the vehicle interrupts the start wire between the Ignition switch
and the starter motor. With the in the
START
position, and the clutch pedal pressed, the relay
energizes and allows the
START
signal to reach the starter motor. In these systems a wires from
the clutch triggers the relay, when the pedal is pressed. There will be another wire at the clutch
switch that supplies the signal to the trigger wire (either positive or negative, depending on the
system)
Negative Systems:
In a Negative system, when the clutch is pressed; a negative signal is sent to the relay,
the relay energizes, when the Key is turned to the
START
position the 12 V from the start
wire is allowed to pass through the relay and to starter motor. One of the wires at the
clutch will test as negative, this is the supply wire. The relay's negative trigger wire will
only show negative when the pedal is pressed ( some vehicle's also require the Ignition
system to be powered). To confirm you have a Negative system, hot wire the negative
trigger wire by jumping it to a ground source with your fused test jumper. You should
now be able to turn the key to the
START
position and engage the start motor, with out
pressing in the clutch pedal. If there is nothing else connected to the Ground Out When
Running (G.O.) wire from the Remote Car Starter, the G.O. wire should be strong
enough to trigger the vehicle's clutch relay. If there are other devices or modules
connected to the G.O. Wire, a relay (and diodes) may have to be added to strengthen the
negative current going to the clutch bypass.
