I used the search button to find out how to install a tachometer into a scion TC. The result is that for the ignition pulse I should use:

"Tachometer black ac data link conn. under dash, pin 9 "

Actually not much help. Can someone post a picture of where this connector is? It says under dash....which side drivers or passangers? And there are a few different black connectors.

Anyone know?

Thanks
Justin

 

Just a quick question, why do you need a tach? It comes with one stock, are you planning on doing engine mods to up the redline?

 

It's for the Apexi Rev/Speed meter

 

Wow, he never got an answer.
