Vehicle Preparation & Wiring
Proper vehicle preparation involves locating and accurately identifying essential wiring diagrams, crucial for successful CompuStar CM5200 series integration and functionality.
Identifying Vehicle Wiring Diagrams
Accurate vehicle wiring diagrams are the cornerstone of a successful CompuStar installation. These diagrams detail the specific wiring configuration for your vehicle’s make, model, and year, pinpointing the location and function of critical wires. Sources for these diagrams include factory service manuals, online databases (often subscription-based), and dedicated automotive wiring resources.
Carefully verify the diagram’s accuracy against your vehicle’s actual wiring harness. Color codes can vary, and modifications may have been made previously. Pay close attention to connector pinouts and wire gauge. Understanding the vehicle’s security system wiring is also vital, as bypassing or integrating with it is often necessary for remote start functionality. Incorrect wiring can lead to system malfunction or vehicle damage, so proceed with caution and double-check all connections.
Locating the Ignition, Starter, and Accessory Wires
Identifying the ignition, starter, and accessory wires is crucial for proper CompuStar functionality. The ignition wire provides power when the key is in the “on” position, while the starter wire activates the vehicle’s starting motor. The accessory wire powers features like the radio and climate control when the key is in the “accessory” or “on” position.
These wires are typically found in the steering column harness. Use a multimeter to verify wire function; testing for 12V when the key is turned to the appropriate position. Consult your vehicle’s wiring diagram for precise wire colors and locations. Accurate identification prevents damage to the vehicle’s electrical system and ensures reliable remote start operation. Incorrect connections can lead to no-start conditions or unexpected system behavior.
Bypassing the Vehicle’s Security System
Modern vehicles often feature sophisticated security systems that can interfere with remote start operation. Bypassing these systems is frequently necessary for successful CompuStar installation. This typically involves utilizing a bypass module, which emulates the vehicle’s key fob signal to disarm the factory security system during remote start.
The specific bypass module required depends on the vehicle’s make and model. Proper programming of the bypass module is essential, often requiring access to a database of vehicle security protocols. Incorrect bypass configuration can result in a no-start condition or trigger the vehicle’s alarm. Always consult the CompuStar bypass module manual and vehicle-specific documentation for detailed instructions.

CompuStar Control Module Installation

Securely mount the control module and connect the main power and ground wires, then carefully wire the vehicle’s starter circuit for operation.
Mounting the Control Module
Selecting a suitable location is crucial for successful CompuStar installation. The control module should be mounted securely in a dry, concealed area within the vehicle, away from direct heat sources and moving parts. Avoid areas prone to water damage or excessive vibration.
