Hi, I'm trying to install a CyberDyne digital Speedometer, but I can't find the signal for the speedometer, could someone please help me. I already try using the diagram from O.T.L. but still can't get a signal.
Thanks in advance

 

is it a 300? maybe this will help

 

yes, I have the sc300, I also have this diagram but have not try it yet cuz I don't want to splice into the ecu harness, I want to use the signal from cluster, do you think it might work? I have 3 signals cuz my auto.
Thank you

 

I found that the speed sensor #2 off the ECM works, it's #23 of 80 plug, not the 40 plug, B23 of the above diagram, pink solid wire.

 

Nice...pics of the install?

 

Yea I'd like to see that definitely.
