Complete 2014 Chrysler 200 Stereo Wiring Guide for Installation
Begin by identifying the factory harness behind the dashboard unit–polarity and voltage specs differ across aftermarket receivers. For models with Uconnect, pin 12 and 16 carry the 12V constant and switched power respectively, while pins 8 (left) and 22 (right) feed the front speaker outputs. Ground connections, typically pins 18 and 24, must retain full contact with the chassis plate to prevent interference.
Use a multimeter at 200 ohms scale to verify continuity between the harness and the new head unit’s wiring harness adapter. Resistance above 0.5 ohms indicates corrosion or loose crimp connections, which will degrade audio clarity. The data bus, pins 3 and 11, requires undisturbed shielding to avoid signal dropouts or erratic behavior in hands-free pairing.
Color-coding follows Chrysler’s standard: dark green/light green for rear left/right, gray/violet for front left/right, and black/white ground. Deviations exist in premium audio variants–twelve-speaker Harman Kardon setups add an additional subwoofer feed on pin 14. Always cross-reference with the vehicle’s build sheet, available through the VIN decoder, to confirm antenna motor activation (pin 6) and illumination dimming (pin 2).
If retrofitting, disconnect the negative battery terminal first to prevent airbag deployment errors or ECU faults. Splice connections using solder joints, not crimp caps–vibration loosens caps over time, causing intermittent failures. For aux-in modifications, tap into pins 4 (left) and 10 (right) with 3.5mm shielded cables, ensuring the ground wire is two gauge sizes thicker than signal wires to minimize noise pickup.
Verify the fuse rating for the audio circuit: a 15A fuse is standard, but 20A may be present in high-current models. Exceeding this trips the circuit and risks overheating the wiring harness, which can melt insulation and short adjacent wires. Keep a spare 15A fuse in the glovebox for on-road replacements.
Audio System Wiring Guide for Mid-Size Sedan Models
Locate the factory harness behind the center console by removing the trim panel secured with clips–avoid forcing tabs to prevent cracking the plastic. The 12-pin connector contains eight critical wires: constant power (yellow, 18-gauge), ignition-switched power (red, 20-gauge), ground (black, 16-gauge with braided shielding), front left speaker (+/-), front right speaker (+/-), rear left speaker (+/-), and rear right speaker (+/-). Use a multimeter set to DC voltage to verify voltages–yellow should read 12V continuous, red 12V only with key in “ACC” or “ON”.
Solder connections instead of twisting or crimping to prevent corrosion and signal loss; apply heat-shrink tubing over each joint. For aftermarket units, match impedance–factory speakers typically handle 2-4 ohms. If installing an amplifier, tap into the yellow wire before the head unit to maintain uninterrupted power; fuse the new line within 18 inches of the battery terminal to comply with safety standards. Avoid routing wiring near engine components or sharp edges; use split loom tubing for protection.
- Pin 1 (yellow): Constant 12V; do not splice–connect directly to battery with inline 15A fuse.
- Pin 4 (black): Ground; attach to chassis using a dedicated bolt, sanding paint for bare metal contact.
- Pin 6 (gray/violet): Front left speaker (+); polarity matters–reverse may cause phase cancellation.
- Pin 8 (red/black): Ignition; must toggle with key to prevent battery drain.
For vehicles equipped with Uconnect, a separate CAN bus interface (16-pin white connector) manages steering wheel controls. If retaining these functions, purchase an adapter harness (e.g., Metra ASWC-1) or map resistors manually–left/right buttons typically require 470kΩ resistors. Test all functions before finalizing trim installation to avoid rework. If static persists after setup, check for loose grounds or interference from alternator; route audio cables perpendicular to power lines to minimize noise.
Replace blown fuses immediately with identical ratings–using higher amperage risks fire. Label all connections with masking tape and document polarities for future reference. If upgrading to a double-DIN unit, the factory climate controls remain integrated; measure the dash aperture at 7.25″ W x 4″ H before purchasing to ensure fitment. For rear cameras, the purple/white wire (reverse signal) activates upon gear shift–ensure it’s routed through the headliner grommet to the tail light housing.
Finding the Stock Audio System Harness Plug in Your Sedan
Begin by removing the climate control trim panel. Use a plastic pry tool to detach the lower dash bezel below the heater vents, starting from the right side near the fuse box cover. The harness connector sits directly behind the HVAC unit–look for a rectangular 24-pin plug with color-coded leads enclosed in a black housing. Gently pull the plug downward to disconnect it from its mount.
Key Connector Pinout Reference
| Pin | Wire Color | Function |
|---|---|---|
| 1 | Dark Green/White | Left Front (+) Speaker |
| 2 | Brown | Illumination Control |
| 4 | Pink | Fused Battery (+12V) |
| 10 | Dark Blue/Yellow | Right Rear (-) Speaker |
| 12 | Gray | Speed Signal Input |
If the harness remains hidden, tilt the glovebox downward after releasing the stop tabs on both sides. The plug may be secured behind a foam block; press upward on the harness bundle to expose it. Verify the plug shape matches the table above before proceeding–aftermarket adapters often require slight adjustments for proper alignment.
Decoding Aftermarket Head Unit Harness Color Standards
Start by locating the 12-volt constant power line–typically a thick yellow wire–before handling any other connections. This wire ensures memory retention for preset stations and settings, even when the ignition is off. Confirm its presence with a multimeter set to DC voltage; readings should consistently show between 11.5 and 14.5 volts.
Ground connections demand a direct, unpainted metal surface on the vehicle’s chassis. Choose a location as close to the original factory ground point as possible to minimize interference. A black wire, often labeled as “Ground,” must be secured tightly with a ring terminal and a bolt or screw to prevent signal noise or intermittent power losses.
Speaker wires follow a standardized color-coding scheme but require verification. Use a 9-volt battery to test each pair–positive and negative–by briefly touching the bare ends to the battery terminals. A faint pop confirms the speaker’s functionality and polarity.
- White/White-Black: Front left (+/-)
- Gray/Gray-Black: Front right (+/-)
- Green/Green-Black: Rear left (+/-)
- Violet/Violet-Black: Rear right (+/-)
- Blue/White: Remote turn-on lead (amplifier trigger)
- Orange: Illumination/dimmer control (adjusts display brightness)
- Purple: Reverse signal (integrates with backup camera feeds)
Avoid assuming factory harnesses match aftermarket units. Cross-reference the vehicle’s service manual with the new stereo’s wiring guide to prevent mismatched connections. For instance, some models combine illumination and dimmer functions on a single wire, while others separate them–overlooking this can result in non-functional dash displays.
Label each wire with masking tape or heat-shrink tubing before cutting or splicing. Use solderless connectors (crimp-style) or solder with heat-shrink insulation for durability. Avoid electrical tape alone–it degrades over time, exposing wires to corrosion. For aftermarket amplifiers, route new power cables away from signal wires to prevent engine noise interference.
How to Secure Power and Ground Connections in Your Vehicle’s Audio System
Locate the constant 12V supply wire–typically a yellow or orange lead–and splice it directly to the head unit’s power input using a crimp connector or solder joint. Ensure the connection is insulated with heat-shrink tubing to prevent short circuits. Verify voltage with a multimeter before finalizing the splice; fluctuations above 14.5V or below 11V indicate alternator or battery issues requiring attention.
Attach the ground cable–a black or brown wire–to a bare metal surface on the chassis, scrubbing away paint or corrosion with sandpaper first. Bolt it securely using a star washer to maintain conductivity under vibration. Avoid common grounding points shared with high-draw accessories like cooling fans or power seats to minimize electrical noise interference in the audio signal.
Route the ignition-switched wire (red or pink) to a fuse tap linked to a circuit that powers on with the key. Use a fuse rated no higher than 10A to prevent overload. Test by turning the key to the “ACC” position; the connection should deliver steady 12V only when the vehicle is active, cutting power entirely when off to avoid battery drain.
For integrated amplifiers, pair the remote turn-on lead (blue/white stripe) with the head unit’s trigger output. Confirm the output voltage matches the amplifier’s activation threshold (usually 3-5V) to avoid premature failure. Double-check all connections with a load test–play audio at 75% volume for 30 minutes–listening for distortion or popping that signals poor grounding or power delivery.
How to Split the Factory Antenna Lead for Retaining AM/FM Functionality
Locate the coaxial input behind the head unit–it’s typically a black Fakra connector labeled “Antenna In.” Use a high-quality signal splitter designed for 75-ohm impedance, such as the PAC SNI-1 or Metra AX-TC2, to preserve signal integrity. Cut the existing antenna cable 4 inches from the connector, strip the outer jacket 0.5 inches back, and expose the braided shield. Twist the shield into a single lead, then strip the inner dielectric to reveal the copper core. Crimp an insulated butt connector to the core and a female spade terminal to the shield, then solder both for durability. Connect the splitter’s input to these terminals, ensuring the shield grounds to the chassis near the mounting point to prevent interference. Route the splitter’s outputs–one to the original antenna, the other to your aftermarket amplifier or tuner–using RG-6 coaxial cable with Fakra connectors if compatible, or solder and heat-shrink for a secure fit. Test AM and FM bands separately; if reception weakens, verify ground connections and splitter insertion loss (should not exceed 0.5 dB).
For vehicles with diversity antennas (dual-band systems), identify the secondary antenna lead–often a thinner coaxial cable–before splitting. Use a dual-output splitter like the Scosche VATI2 to feed both the primary and diversity inputs. Avoid daisy-chaining splitters; each additional split can degrade signal strength by 3–4 dB. If static occurs on AM, bypass filters in the splitter that may attenuate lower frequencies (AM band ranges from 530 to 1700 kHz). For persistent issues, install an inline signal booster (e.g., Terk AFBS) between the antenna and splitter, ensuring it’s rated for both bands. Secure all connections with dielectric grease to prevent oxidation, especially in humid climates.
