CA 521 SYSTEM LAYOUT

1. SIX PIN POWER HARNESS

Battery Power 1 (RED)

Battery Power 2 (RED)

Locate the vehicle battery wire(s) at the ignition switch.

Verification: These wires will register voltage in all positions of the ignition switch.

Connect the RED wires to the vehicle’s battery wire.

Note: Remove the 30 Amp fuse out of each fuse holder until the installation is complete

IMPORTANT!

If the vehicle is equipped with more than one battery wire at the ignition switch, connect the RED

wiretoseparatevehiclebatterywires.

Starter Output (PURPLE)

Locate the vehicle’s starter wire at the ignition switch.

Verification: This wire registers voltage only in the start (crank) position of the ignition switch.

Connect the PURPLE wire to the vehicle’s starter wire.

Ignition 1 Output (PINK)

Locate the vehicle’s Ignition 1 wire at the ignition switch.

Verification: This wire registers voltage when the key is turned to the ON (or RUN) position. The voltage

does not drop out when the key is turned to the START(or CRANK) position.

Connect the PINK wire to the vehicle’s Ignition 1 wire.

Accessory 1 (Heater/AC) Output (ORANGE)

Locate the vehicle’s accessory wire at the ignition switch.

Verification: This wire registers voltage when the key is turned to the ON (or RUN) position, but not the ACC

(Accessory) position. The voltage drops out when the key is turned to the START(or CRANK) position.

Selectable Ignition 2 Output / Accessory 2 Output (PINK/WHITE)

Locate the vehicle’s ignition 2 or accessory 2 wire at the ignition switch. Refer to the Ignition 1 or Accessory

1 wires above for verification.

Connect the PINK/WHITE wire to the vehicle’s ignition 2 or accessory 2 wire.

IMPORTANT!

The factory setting for the PINK/WHITE wire is ignition 2 output. Refer to programming option 2 on

page14to change the settingtoaccessory 2 output.

2. THIRTEEN PIN HARNESS

Chassis Ground Source (-) (BLACK)

Connect the BLACK wire to a solid chassis ground point using the supplied ring terminal and 1/2” long

screw. Scrape away paint from the grounding point to ensure a good connection. The recommended

grounding point is a painted metal surface in the driver’s side kick panel area.

Note: Do not ground the BLACK wire with any other vehicle components.

Hood Pin Input / Shutdown (-) (GRAY)

Mount the supplied hood pin switch in an area allowing the hood to depress the switch at least 1/4” when

closed. Use care to make sure the hood pin switch is mounted away from water drain paths. If necessary,

the included bracket may be used to mount the hood pin switch away from rain gutters or for mounting

against the fire wall. Carefully check behind the chosen location for fluid lines or electrical wiring. The hood

pin switch must be mounted into a metal chassis ground surface.

For direct mounting, drill a 1/4” hole and thread the hood pin switch into the hole and tighten with a 7/16”

nut driver.

Route the GRAY wire through an existing grommet (if available) in the firewall and connect to the mounted

hood pin switch.

IMPORTANT!

The hood pin switch will prevent the vehicle from remote starting if the vehicle’s hood is open.

Failure to install the hood pin switch may result in personal injury or property damage.

Brake Input/Shutdown (+) (BROWN/RED)

Locate the vehicle’s ignition coil or fuel injector in the engine compartment.

Verification: Refer to Vehicle Wire Color and Location Chart for the wire color and location, or test using

the following procedure:

1. Set voltmeter toAC VOLTS.

2. Attach positive lead of the volt meter to a constant 12-volt source.

3. Attach negative lead of the volt meter to the wire being tested.

4. Start the engine.

5. Have someone press on the gas pedal slightly as you monitor the meter. If connected to the correct

wire, the voltage reading will increase as the engine’s RPM increases.

Connect the PURPLE/WHITE wire to the negative side of the vehicle ignition coil or fuel injector.

2. THIRTEEN PIN HARNESS, CONTINUED

Wait-To-Start Input (+) (GRAY/BLACK)

Locate the Wait-To-Start light wire at the instrument panel.

Verification: This wire registers positive or negative voltage when the wait-to-start light illuminates.

For Positive switching circuits follow the diagram below.

For Negative switching circuits follow the diagram below. Use Code Alarm part HDRLY (an SPDT relay, not

included).

NOTE!

The CA-521 has an optional Wait-To-Start feature that provides a pre-set wait-to-start time.

When using this feature it is not necessary to connect the GRAY/BLACK wire above.

Active Output (-) 300mA (BLUE/BLACK)

The Ignition 3 output wire provides a ground output when the remote start function is activated and remains

active for 4 seconds after the remote start is shutdown. The Ignition 3 output wire can be used for several

functions listed below. If this wire will be used for multiple applications a 1 amp diode is required inline

with the stripe facing the control module.

Factory transponder (coded key) bypass. See your sales associate for details.

General Motors VATS bypass, see diagram 3 below. Use Code Alarm part HDRLY (an SPDT relay, not

included).

Ignition 3 output, see the diagram on the left below. Use Code Alarm part HDRLY (an SPDT relay, not

included).
