My tach in my 03 Evo does not work and i want to check the wires behind the cluster and make sure that the tach wire is good. What color or pin # is the tach wire that goes into the back of the cluster? I know that pin 58 on the ecu is the tach signal (green / white) but cannot find a green/white wire that goes to the back of the cluster. Can anyone help me.

 

Best I can tell is Green, pin 11?


In plug C-01 which is pictured here

 

wow i have no idea how you got that with those pics

 

Pin 11 in plug C-01 is your tach signal. Origin is pin 58 in ECU plug C-117.

See section 54A-60 in 'Chassis electrical - Combination meter assembly and vehicle speed sensor' - inspection procedure 2 - tachometer does not work

 

thank you very much. I will try and see if i am getting power to that wire and try and get my damn tach working again.

 

i checked the wire and i am not getting any power going to it i dont believe. I tried with the car on and off. I am not sure exactly how to use my multi meter but shouldnt it have around 12 volts when the car is running?

 

The tach wire at the cluster should read between 1-7 volts AC, not DC. And will increase and decrease based on engine speed.

 

Im having the same issue, What color is the wire off which color connector the blue one or the grey one is the tach signal.

 

i think its the connector on the left side if you're sitting in the drivers seat
