LS3 Speed signal
I have a 2008 LS3 480hp with GM Performance harness. How do I get a speedometer signal? There is a bulk head connector, but how do I get a wire to it? This is in '72 Chevelle. Any suggestions how to get the electric signal to work with a OEM speedometer?
Thank you!

The 1972 Chevelle's had cable driven mechanical speedometers so their speedometers would be driven off the side of the transmission.
