INTRODUCTION 

 
INSTALLER WARNINGS 

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

 

Never install this remote starter on a manual 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. 

 

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.
