WIRING
 
Keep wiring away from moving engine parts, exhaust pipes and high-tension cable. Tape wires that pass through holes on 
the firewall to prevent fraying. Watch out for sharp edges that may damage wires and cause a 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 CONNECTIONS: 
 
Remember! What the system does to start a vehicle, duplicates the function 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 has +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 neutral safety switch can result in personal injury and property 
damage. SEE NEUTRAL START SAFETY TEST FOR FURTHER DETAILS.

H1/2 & H1/3. RED WIRE (2)-- +12V Power Input
Remove the two 20A fuses prior to connecting these wires and do not replace them until all connectors have been plugged 
into the control module. These wires are the source of current for all the circuits the starter unit will energize. They must 
be connected to a high current source. Since the factory supplies (+) 12V to the key switch that is used to operate the 
motor, it is recommended that these wires be connected there. 
Note: If the factory supplies two separate (+) 12V feeds to the ignition switch, connect one RED wire of the unit to each 
feed at the switch. 
H1/4. YELLOW WIRE – Ignition 1 Output
Connect the YELLOW wire to the ignition 1 wire from the ignition switch. The ignition wire should receive "12 volts" when 
the ignition key is in the "ON" or “RUN” and "START" or “CRANK” position. When the ignition is turned "OFF", the ignition 
wire should receive "0" voltage. The YELLOW wire must be connected. 
H1/5 PINK WIRE – Ignition 2 Output
Some vehicles have [2] ignition wires that must be power. Connect the PINK wire to the ignition 2 wire from the ignition 
switch. The ignition wire should receive "12 volts" when the ignition key is in the "ON" or “RUN” and "START" or “CRANK” 
position. When the ignition is turned "OFF", the ignition wire should receive "0" voltage. If the PINK wire is not used, cap 
the end of the wire. 
H1/6 BROWN WIRE – Accessory Output (Heater /ACC Output) –
