View Full Version : How do I wire up the stock speed sensor?

07-26-2005, 09:21 AM
I have a 98 Sr20 in my 71 240Z. And I have the Defi Heads up display speedo. I have the listening signal wire from the Defi heads up spliced into the yellow/Green ECU Pin 32. But now i have no clue what I need to do with the "2" wires coming from the sensor. Please dont tell me to run them into my the gauge cluster becuase this is a 240Z with all Defi Gauges.

What I am asking is, Is there a way to wire up this VSS without the stock gauge cluster? And if so..How? Thanks alot! :)

signal is most often paired with a ground wire..
