1. Turn the Ignition 'switch to ‘ON position.   
2. Press the

 

 

button on the transmitter.

TESTING YOUR INSTALLATION: 

Caution!! 

The follow procedure must be performed after the installation of the Remote Start Device. It is the 

responsibility of the installing technician to complete these tests. Failure to test the unit in the following 
manner may result in personal injury, property damage, or both. 
1. Test the BRAKE shutdown circuit: With the vehicle in park (P), start the vehicle using the remote 

transmitter, Once the engine is running, press the brake pedal. The vehicle should shut down immediately. 
If the vehicle continues to run, check the brake circuit WHITE/ VIOLET

 

wire (H6/3) connection.   

2. Test the HOOD PIN shutdown circuit: Start the vehicle using the remote transmitter, Once the engine is 

running, pull the hood release and raise the hood. The vehicle should shut down immediately. If the 
vehicle continues to run, check the hood pin WHITE/ BLACK wire (H6/4) connection.   

3. NEUTRAL START SAFETY TEST:   

1. Set the vehicle parking brake. 
2. Block the drive wheels to prevent vehicle movement. 
3. Sitting in the vehicle, turn the ignition switch to “ON” or “RUN” position. But do not start the engine. 
4. Step on the brake pedal and shift the gear selector into “DRIVE” (D). 
5. Put your foot over the brake pedal but do not press down on it. Be ready to step on the brake to shut 

down the Remote Start Device. 

6. Start the vehicle using remote transmitter. 

a. 

If the starter does not engage, the test is complete. 

b. 

If the starter engages, immediately step on the brake pedal to shut down the system, recheck your 
VIOLET wire (H1/1 starter output wire) connection. The heavy gauge VIOLET wire must be 
connected to the ignition switch side of the Neutral Start Switch. If the vehicle you are working on 
does not have an Electrical Neutral Safety Switch, it will be necessary to reconfigure the Remote 
Starts Wiring to accommodate this vehicle. The information concerning the Mechanical Neutral Safety 
Switch provided below will help you to determine if the vehicle you are working on has this type of 
safety switch and will provide alternate wiring methods to accommodate this situation. 

MECHANICAL NEUTRAL SAFETY SWITCH CONSIDERATIONS: 

Mechanical neutral safety switch configurations differ slightly in that they do not offer the same level of safety 
when installing a remote start device. Often when the ignition switch is turned off while the gear selector is in 
any position other than park or neutral, the mechanical function will not allow the key to be turned to the start 
position or be removed from the ignition cylinder. This configuration prevents mechanical operation while the 
vehicle is in gear but offers no consideration for electrical operation. Because of this potential problem, this
