HiThe sw/ws is black wire with white trace pin 2 on the cluster, that is the MPH signalThe sw black wire pin 20 on the cluster is the RPM signal. There is the 2 wires.

Sent you image of back of instrument panel. Please send image noting WHICH cluster of wires you are referring to.
Wire #2 is noted as turn signal.
Expert:  MartinsMotorSport replied 1 year ago.
Cluster is another name for the instrument panel.
Pin 2 is on the x17 connector.(back of panel)
Pin 20 is on the x16 connector.(back of panel)
both connectors is on the back of the instrument panel.
so if you look at the plugs and pull the cover off the plug, you will see on pin 20 a black wire, then that is x16 connector and you can tap into that wire
and if you look at the other connector you should find in pin 2 a black wire with white stripe, that is the other wire you can tap into.
Let me know if you come right :)
