# BMW F30 Gateway connection guide Here is the guide for connecting the PT\_CAN, PT\_CAN2, power, fan control, and accelerator pedal signals to the Gateway device and ECU. The main connections needed for this modifications are: [[BMW F30 A46*1B pinout|**A46\*1B**]], pinout|**A46\*1B**]] , [[BMW F30 X13*1B pinout|**X13\*1B**]], and [[BMW F30 Z8*3B pinout|**Z8\*3B**]] pinout|**Z8\*3B**] connectors. This guide is based on N20/N26 engine and DME. Connections for B46/B48 and B58 may be different. Before you start, please familiarize yourself with: * [[CAN Gateway Pinout]] * [[BMW F30 A46*1B pinout]] * [[BMW F30 X13*1B pinout]] * [[BMW F30 Z8*3B pinout]] ### PT\_CAN to Gateway Device: - **PT\_CAN\_H**: - **Pin 28 on A46\*1B (Blue/Red wire)** should be connected to **CAN1H (Pin 10 on your Gateway device)**. - **PT\_CAN\_L**: - **Pin 13 on A46\*1B (Red wire)** should be connected to **CAN1L (Pin 23 on your Gateway device)**. ### PT\_CAN2 to Gateway Device: - **PT\_CAN2H**: - **Pin 43 on A46\*1B (White/Yellow wire)** should be connected to **CAN2H (Pin 11 on your Gateway device)**. - **PT\_CAN2L**: - **Pin 44 on A46\*1B (White/Blue wire)** should be connected to **CAN2L (Pin 24 on your Gateway device)**. ### Power and Ignition Connections to Gateway Device: - **KL30 (Battery Power Supply)**: - **Pin 1 on A46\*1B** should be connected to **KL30 IN (Pin 1 on your Gateway device)**. - **KL15 (Ignition Supply)**: - **Pin 22 on A46\*1B** should be connected to **KL15IN (Pin 15 on your Gateway device)**. ### Fan Control Connections: - **Fan Cut-Out Relay**: - **Pin 4 on A46\*1B** is used for the fan cut-out relay and should be controlled by the **ECU**. - **Fan PWM Signal**: - **Pin 18 on A46\*1B** is the fan PWM signal and should also be controlled by the **ECU**. ### Accelerator Pedal Connections: - The **accelerator pedal** should be connected to the **ECU** or to the **analog inputs on the Gateway device** in case you want to send throttle position over the CAN bus. - **5V Supply for Accelerator Pedal**: - **Pins 7 and 24 on A46\*1B** provide the 5V supply for the accelerator pedal. - **Ground for Accelerator Pedal**: - **Pins 11 and 27 on A46\*1B** are the ground connections for the accelerator pedal. - **Signals for Accelerator Pedal**: - **Pins 16 and 21 on A46\*1B** are used for the two signal outputs from the accelerator pedal. ### X13\*1B Connector Connections: - **Pin 1 and Pin 11**: - These pins control the **AC compressor** on the engine. Both components are controlled by the **FEM** (Front Electronic Module), and it is recommended to use the original BMW AC compressor. - **Pin 9**: - This pin controls the **starter**. It is capable of driving a **2JZ starter** and is also controlled by the **FEM**. ### Z8\*3B Connector Connection:  - **KL31 (Ground)**: - **Pin 3 on Z8\*3B** should be used as **KL31** for the Gateway device. - **KL15 (Ignition Supply for ECU)**: - **Pin 1 on Z8\*3B** should be used to control the main relay for the standalone ECU. ### Notes: - Ensure that all connections are securely made and wires are properly insulated. - For CAN signals, use twisted pairs to minimize electromagnetic interference, ensuring the integrity of communication between the vehicle and the Gateway device. - Double-check all connections to prevent any miswiring that could damage components or cause malfunction.
