📊 Pin Mapping Reference

2015+ BCM Missing Connections

These pins on the newer BCM need connections from your 2011-14 vehicle harness:

Connector	Pin	Function
C1 – A	22	Right DRL Lamp Driver
C4 – D	15	Left DRL Lamp Driver
C5 – E	14	Left Stop Lamp Fault Sense
C6 – F	13	Liftgate Handle Switch Sense
C6 – F	27	Left Rear Door Ajar Switch Sense
C6 – F	28	Right Front Lighting Fault Sense
C6 – F	31	Right Stop Lamp Fault Sense

2014 Original BCM Connections

These pins from your original 2014 BCM need to be identified and transferred:

Connector	Pin	Function
C5 – E	3	Left Rear Turn Lamp Driver
C5 – E	32	Left Rear Door Ajar Switch Sense
C5 – E	35	Adjustable Pedals Relay Control
C6 – F	42	Right Rear Turn Lamp Driver

🔌 Critical Pin Transfers

Key Wiring Changes Required

Left Rear Door Ajar Switch

This connection changes location between old and new BCM:

Old: C5 / E – Pin 32 (2014 BCM)
New: C6 / F – Pin 27 (2015+ BCM)

⚠️ You must move the door ajar sense wire from the old pin location to the new pin location on the updated BCM connector.

All Wires to Relocate

Wire Function	From (2014)	To (2015+)	Wire Color Tip
Left Rear Turn Lamp	C5 – E / Pin 3	Map to 2015+ equivalent	Typically brown/yellow stripe
Right Rear Turn Lamp	C6 – F / Pin 42	Map to 2015+ equivalent	Typically brown/orange stripe
Left Door Ajar	C5 – E / Pin 32	C6 – F / Pin 27	Typically green wire
Adjustable Pedals	C5 – E / Pin 35	Map to 2015+ equivalent	Purple/white stripe

🔧 Step-by-Step Swap Instructions

Disconnect Battery & Remove Old BCM

Disconnect the negative battery terminal. Remove plastic covers from kick panels and locate the BCM (typically driver side under dash). Unplug all four connectors (C1-C4 or C5-C8 depending on labeling). Take photos of connector positions for reference.

Document Original Wiring

Before making any changes, photograph each connector with pin numbers clearly visible. Use a multimeter to test voltage on key pins. Label and color-code wires from the original BCM to identify which ones go where on the new unit.

Prepare New 2015+ BCM

Place new BCM next to old unit. Compare connector layouts. The connectors may have different pin counts. You’ll need to move wires from old connector positions to new pin numbers as shown in the Pin Mapping Reference above.

Transfer Critical Wires

Using the pin mapping table above, carefully remove wires from the old BCM connectors and install them into the correct pins on the new BCM. Use proper crimpers to ensure solid connections. The door ajar sense wire (green) must move from C5-E-Pin32 to C6-F-Pin27.

Install New BCM

Mount the new BCM in the same location. Connect all four connectors firmly until they click. Double-check each connector for proper seating and secure any loose wires with clips or zip ties.

Reconnect Battery & Test

Reconnect the negative battery terminal. Turn ignition to ON (don’t start). Check for dashboard warning lights. Connect diagnostic scanner to check for DTCs. If no critical errors appear, proceed to programming steps.

⚠️ Common Mistake
Many installers forget that pin numbers don’t always correspond between old and new connectors. The 2015+ BCM has DIFFERENT PIN LAYOUTS. You cannot simply move connectors—you must move individual wires to the correct pins as specified in this guide.

📢 Horn Module Modification

The horn requires a dedicated wire between the Steering Column Control Module (SCCM) and the new BCM.

Yellow Steering Column Connector

Your vehicle has a yellow 14-pin connector in the back of the steering column. This is where you’ll add the horn circuit.

ℹ️ Connector Location
The yellow 14-pin connector is located behind the steering column upper shroud. You may need to remove the plastic cover to access it.

Component	Connector	Pin	Function
SCCM	Yellow 14-pin	6	Horn Switch Sense (out)
New BCM	C6 – F	29	Horn Switch Sense (in)

Horn Installation Steps

Locate Yellow Connector

Remove steering column cover. Find the yellow 14-pin connector at the back of the steering column.

Add Pin to SCCM

Insert a new pin into position 6 of the yellow SCCM connector. Use proper automotive-grade connectors and crimp the wire securely.

Run Wire to BCM

Run a wire from SCCM pin 6 through the dash to the BCM location. Use existing wire loom where possible to keep the install clean.

Connect to New BCM

Connect the horn sense wire to C6-F-Pin29 on the new BCM. This completes the horn circuit between steering wheel controls and the module.

💡 Pro Tip: Test Horn Function

Before buttoning up, test the horn by pressing the steering wheel pad
If horn doesn’t work, check pin 6 on SCCM is properly seated
Use multimeter to verify voltage at pin 29 on BCM when horn is pressed

🌐 LIN Bus Configuration

Lin Bus CBC 3 Connection

Network	BCM Connector	SCCM Connector
LIN Bus CBC 3	C4 – D / Pin 17	Yellow / Pin 1

The LIN bus (Local Interconnect Network) allows communication between the BCM and SCCM. This wire typically carries the diagnostic and control signals between modules. Ensure this connection is solid.

🔍 DTC Diagnostics & AlfaOBD Settings

The 2015+ BCM includes diagnostic monitoring for the 3rd lighting wire that doesn’t exist on your 2011-14 Charger. You’ll see DTCs for these circuits—don’t panic, they’re normal and can be disabled.

Disabling Unnecessary DTCs

⚠️ Important
Use AlfaOBD or similar diagnostic software to search for and disable DTCs related to missing diagnostic lamp wires. Common codes include:

U0401 – Right DRL diagnostic fault
U0402 – Left DRL diagnostic fault
U0403 – Stop lamp diagnostic fault
U0404 – Rear turn signal diagnostic fault

📱 AlfaOBD Steps

Connect OBD scanner
Open AlfaOBD software
Navigate to BCM module
Search for “DTC” in settings
Disable lighting diagnostic codes
Save changes to BCM

✓ Post-Programming Checks

All lights work (DRL, brake, turn)
Door ajar warning functions
Horn operates normally
No critical DTCs remain
Dashboard warns gone

💡 Pro Tip: Keep DTC Notes

Screenshot all DTCs before and after programming
Document which codes you disabled and why
This helps with future diagnostics or resale

❓ Frequently Asked Questions

Q: Why does the 2015+ BCM have those extra diagnostic wires?

A: Starting in 2015, Dodge/Chrysler added a third wire to every lighting circuit for diagnostic monitoring. This allows the BCM to detect bulb failures, open circuits, and shorts more accurately. Your 2011-14 Charger doesn’t have these wires, so the BCM codes them as faults. Simply disable the DTCs in AlfaOBD.

Q: Is this swap reversible?

A: Yes, but with caution. Keep your original BCM and document all pin positions. If you ever need to go back to factory 2014 BCM, you’ll know exactly where each wire goes. However, the upgrade is typically permanent once complete.

Q: Will my car’s warranty be affected?

A: This modification will void dealer warranty on electrical components. If you need warranty work, you may need to reinstall the original BCM. This is why documentation is important.

Q: What if I mix up the wire transfers?

A: Wrong connections can cause electrical shorts, blown fuses, or disabled features. This is why taking photos before disassembly is critical. Use the pin mapping tables in this guide as your reference. When in doubt, trace the wire back to the old BCM and match it to the new one’s equivalent function.

Q: Can I do this without AlfaOBD?

A: Technically yes, but AlfaOBD or similar OBD software is strongly recommended. You’ll want to clear DTCs and verify everything works properly. A generic scanner won’t have access to detailed BCM programming.

Q: How long does the actual swap take?

A: The physical swap (removing old, installing new, wiring changes) typically takes 2-3 hours for an experienced installer. Add another 30-45 minutes for programming and testing. First-timers should budget 4-5 hours total.
