INSTALLER WARNINGS 

This Remote Starter with Alarm System is designed to be installed on fuel injected vehicles ONLY.   

 

For automatic transmission vehicle, this system must be installed and wired through a safety switch it will 

not start in any forward or reverse gear. 

 

Some automatic transmission vehicle [mainly older GM vehicles with a purple starter wire] have a 

mechanical-type park safety switch instead of electrical safety switch. The mechanical type does not interrupt 
the starter circuit when the transmission is any gear and does not offer the 100% level of safety required for 
remote starting purposes. Therefore, our system should never be installed on any vehicle that uses a 
mechanical type park safety switch. 

 

For automatic transmission vehicle, once you install this system, you must verify that the vehicle will not 

start any forward or reverse gear. Regardless of the type of vehicle. 

 

Read operation manual for operating and programming routine. 

 

Do not install any component near the brake, gas pedal or steering linkage. 

 

Some vehicles have a factory installed transponder immobilizer system that can severely complicate the 

installation. There is possibility that this system can not be installed on some immobilizer equipped vehicles. 

 

Most vehicles have an SRS air bag system. Use extreme care and do not probe any wires of the SRS 

system. 

 

Disconnect the car battery before connecting work on the vehicle. 

 

Check behind panels before drilling any holes. Ensure that no wiring harness or other components are 

located behind the panels that would otherwise be damaged. 

 

Use conventional crimp lock, bullet on any wiring. Poor wiring, i.e. taped joints will possibly introduce 

unreliability into the alarm system and may result in false alarms or incorrect operation. 

 

Install wiring neatly under carpets or behind trim to prevent possible damage to wires. 

 

For the wire operates the current more than 10A. We suggest soldering all connection point. Do not use 

crimp lock type connectors or wire nuts. 

 

WIRING 

Keep wires away from moving engine parts, exhaust pipes and high-tension cable. Tape wires that pass 
through holes on firewall to prevent fraying. Watch for sharp edges that may damage wires and causes short 
circuit. 
CAUTION: Do not connect the wire harness to the control module until all wiring to vehicle is complete. 

H1: 6 PIN HEAVY GAUGE WIRING CONNECTION: 

Remember that the system does to start a vehicle is duplicate the functions of the ignition key switch! Below, 
we will explain the three basic functions of the ignition switch. Since this installation will require analysis of 
the ignition switch functions, we recommend making the three connections below at the ignition switch 
harness directly.   

H1/1. Violet Wire – Starter Output 

Careful consideration for the connection of this wire must be made to prevent the vehicle from starting while 
in gear. Understanding the difference between a mechanical and an electrical Neutral Start Switch will allow 
you to properly identify the circuit and select the correct installation method. In addition you will realize why 
the connection of the safety wire is required for all mechanical switch configurations. 
Failure to make this connection properly can result in personal injury and property damage. 
In all installations it is the responsibility of the installing technician to test the remote start unit and assure that 
the vehicle can not start via RF control in any gear selection other than park or neutral. 
In both mechanical and electrical neutral start switch configurations, the connection of the VIOLET wire will 
be made to the low current start solenoid wire of the ignition switch harness. This wire have +12 volts when 
the ignition switch is turned to the “START” (CRANK) position only. This wire 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 neutral safety switch can result in personal injury 
and property damage. SEE NEUTRAL START SAFETY TEST FOR FURTHER DETAILS.
