After researching, I found a possible pinout for the Mitsubishi 4M51 ECU:

It's important to understand why a simple table of pin numbers and functions can be misleading. The actual pin assignment on your 4M51 ECU can vary based on several key factors: mitsubishi 4m51 ecu pinout top

| Pin # | Signal Name | Description | | --- | --- | --- | | 16 | Vehicle Speed Sensor (VSS) | Vehicle Speed Sensor | | 17 | Transmission Control Switch | Transmission Control Switch | | 18 | A/C Compressor Clutch Relay | A/C Compressor Clutch Relay | | 19 | Fan Relay | Cooling Fan Relay | | 20 | Fuel Heater Control | Fuel Heater Control | | 21 | Intake Manifold Pressure Sensor (MAP) | Intake Manifold Pressure Sensor | | 22 | Exhaust Gas Pressure Sensor (EGPS) | Exhaust Gas Pressure Sensor | | 23 | DPF Differential Pressure Sensor | DPF Differential Pressure Sensor | | 24 | Lambda Sensor | Lambda Sensor ( Oxygen Sensor) |

Do not pierce the insulation of wires with sharp probes during testing. This allows moisture infiltration, leading to green copper corrosion over time. Always back-probe the plug connector face or use a break-out box. This public link is valid for 7 days

The rain in the salvage yard outside of Osaka didn’t wash away the grease; it only made the rust smell sharper. Kenji wiped his hands on a rag that was dirtier than his skin and stared at the beast before him.

: Dedicated pins for chassis ground and sensor ground (e.g., Pins 8 and 36). Sensor Inputs Engine Speed (Crankshaft/Camshaft) : Pins 22 (CRS Position) and 14 (Camshaft V). Coolant Temperature (CTS) Intake Air/Boost Pressure : Pins 13 (Supply) and 25 (Signal). Pump Controls (Critical for 4M51) Spill Valve (SCV) Can’t copy the link right now

: Connections for the Crankshaft Position (CKP), Camshaft Position (CMP), Rail Pressure, and Intake Air Temperature (IAT) sensors.

Sends direct signals to modulate fueling amounts across various engine speed variables. 3. Sensor Arrays & Monitoring Feed Inputs
