Prestige APS-57E Installation Manual page 7

In both mechanical and electrical neutral start switch configurations, the connection of the Yellow Wire will be
made to the low current start solenoid wire of the ignition switch harness. This wire will have +12 Volts when
the ignition switch is turned to the start (crank) position only. This wire will have 0 Volts in all other ignition
switch positions.
NOTE: This wire must be connected to the vehicle side of the starter cut relay (when used). For the
electrical neutral switch configuration, this connection must be made between the starter
inhibit relay, ( when used ) and the neutral safety switch as shown in the following diagram.
Failure to connect this wire to the ignition switch side of the of the neutral safety switch can result in
personal injury and property damage.
SEE NEUTRAL START SAFETY TEST FOR FURTHER DETAILS.
WIRING CONNECTIONS: 14 Pin Accessory Input/Output Harness
1 Green w/ Orange Trace Wire: Tachometer Input Signal
This wire will continually monitor the engine's tach rate while the unit is under the power of the Remote
Start module. This wire will be routed to the vehicle ECM tach input or through the firewall into the engine
compartment and connect to the negative side of the ignition coil. This Remote Start unit learns the tach rate
of the vehicle and in most cases will operate properly from one coil pack regardless of the number of cylinders.
If the unit has difficulty sensing a single coil, this input can connect to an injector wire as an alternate.
NOTE: For Hybrid mode selection, Bank 3 feature selection 5, this connection is not required, the unit will
start the vehicle and run the allotted time based on feature selection and crank duration.
2 Green w/ Yellow Trace Wire: Diesel Wait To Start Input
The Green w/Yellow Trace Wire, when connected to the wire that gets +12 Volts during the glow plug preheat
stage will delay the starter output until this wire drops the 12 Volts. In other words, in a Diesel vehicle with
glow plug preheat circuit, when the ignition is turned on, the vehicle will not crank until the glow plugs are
hot enough to fire the atomized fuel oil when injected into the cylinder. By connecting this wire to the glow
plug +12 Volt wire, when the remote start unit activates the ignition one output, the glow plug output also
activates. The remote start sees the green/yellow with positive voltage and waits for this to go inactive (drop
to 0 Volts) before activating the starter motor. If this wire is not used or you have difficulty accessing the glow
plug preheat circuit, you may elect to utilize the Diesel timed output as specified in Remote Start feature
selection Bank 3 Feature #12.
NOTE: If the Green w/Yellow Trace Wire is used, it will override or negate any setting of Bank 3 feature #12.
