Strengthening Current:

Example: Strengthening an output

Problem: A vehicle has a negative (-) trigger trunk release wire. The module has a negative trunk release

output wire. The remote start module is unable to supply the necessary current to activate the vehicle's trunk

release wire.

Solution: A relay is used to provide the necessary negative current to active the vehicle's trunk release wire.

The Relay Connections

85: Connects to the start module's trunk release wire output. This becomes the negative trigger for the coil.

86: Connects to a fused +12 volt source.

87: Connects to a negative source (where the remote start module is grounded). This becomes the supply for

activating the vehicle's trunk release wire.

87A: No connection. This terminal is not used in this application.

30: Connects to the vehicle's trunk release wire.

Comments: At rest the relay is not active and the vehicle's trunk release switch is allowed to operate normally.

When the trunk release button is pressed, the start module's trunk release output activates the relay. The

ground signal is sent from 87 through 30 to the vehicle's trunk release wire activating the switch and opening

the trunk.

ClutchBypass

In order to remote start a manual transmission vehicle, the clutch switch must be bypassed. Clutch safety

switch circuits can take many forms. Listed below are the most common ones. When testing to determine the

type of clutch circuit, it is recommended to use a computer safe logic probe. Some vehicles may also have a

separate or combined switch on the clutch pedal for cruise control. Usually a cruise control switch reacts the

moment you touch the pedal, where as a clutch switch reacts only when the pedal is near the floor. Once the

circuit type has been determined, you must recreate what happens electrically at the switch, with the remote

start module, to bypass the clutch during remote starts. Relays are often used to accomplish this. Always use

the Ground Out When Running (G.O.) as the negative trigger on your clutch bypass relays, as it is only active

during remote starts.

NEVER permanently bypass a clutch switch. Do not attempt this if you are unfamiliar with the use of relays,

and diode isolation.

Before any Hot wiring attempts:

Test and record the way each wire tests in the following positions:

With out the pedal pressed:

• test the wires with the Ignition OFF

• test the wires with the Ignition ON

• test the wires with the Key in the start position

With the pedal pressed:

• test the wires with the Ignition OFF

• test the wires with the Ignition ON

• test the wires 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

+12v 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 12v 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 in the crank position, the other wire will also read 12 volts; this is the solenoid side wire. To

confirm you have a direct feed clutch switch, hot wire the “solenoid side” wire with a fused +12 volts and the

starter motor will crank. Connect the starter output from the remote starter to solenoid side wire.
