Odie55,

Check out this page and all the T5 related links and info offered by our very own member "Lugnutz".

https://lugnutz65chevystepside.weebly.com/t5-info-page.html

There some great pictures that show the difference between a cable driven and VSS sensor connector on T5s (to help us know which setup your T5 has).

I think once you can confirm which speedometer drive setup you have, folks can better try and provide suggestions on connecting to your existing mechanical speedometer.

Let us know so we can continue to try and help.

Dan
