I was wondering if anyone has a diagram of the ecu and knows what each pin does, i'm trying to install my air/fuel ratio gauge by hooking it up to the ecu, any help would be appreciated thanks again

This is for a 2006 TL 6MT and A/T ECU, 04/5 could be different:
...................................pinout color
Ignition Coil 1...............A20 YEL/GRN
Ignition Coil 2...............A19 BLU/RED
Ignition Coil 3...............A18 WHT/BLU
Ignition Coil 4...............A17 BRN
Ignition Coil 5...............A16 BLK/RED
Ignition Coil 6...............A15 BRN/WHT
Injector 1.....................A21 BRN
Injector 2.....................A31 RED
Injector 3.....................A30 BLU
Injector 4.....................A29 YEL
Injector 5.....................A28 BLK/RED
Injector 6.....................A27 WHT/BLU
VTEC solenoid..............A22 GRN/YEL
MAP sensor..................C5 GRN/RED
Crank sensor...............B17 BLU
Cam sensor.................B8 YEL
Knock sensor...............B6 RED/BLU
IAT sensor...................A5 RED/YEL
Speed sensor..............B19 BLU
Pedal position sensor..D3 RED/BLU
Ignition........................D6 BLK/GRN
Ground........................A1 BLK
Sensor Ground............D7 GRN

 

Ok, there you go 04/5 ECU, some difference:

...................................pinout color
Ignition Coil 1...............E20 YEL/GRN
Ignition Coil 2...............E19 BLU/RED
Ignition Coil 3...............E18 WHT/BLU
Ignition Coil 4...............E17 BRN
Ignition Coil 5...............E16 BLK/RED
Ignition Coil 6...............E15 BRN/WHT
Injector 1.....................E21 BRN
Injector 2.....................E31 RED
Injector 3.....................E30 BLU
Injector 4.....................E29 YEL
Injector 5.....................E28 BLK/RED
Injector 6.....................E27 WHT/BLU
VTEC solenoid..............E22 GRN/YEL
VTM VTEC pressure......E23 BLU/BLK
MAP sensor..................D5 GRN/RED
Crank sensor...............D1 BLU/RED
Cam sensor.................D7YEL
Knock sensor...............B6 RED/BLU
IAT sensor...................D16 RED/YEL
Speed sensor..............D14 BLU
Pedal position sensor..D3 RED/BLU
Ignition........................E4 YEL/BLK
Ground........................E1 BLK
Sensor Ground............E2 BLK
