Hi, I have normal stack gauges,looking at maybe getting prosport ones, I have boost and oil pressure, can I use the existing wires and just swap over the gauges?

 

prosport stepper gauges have their own connectors that come with them, i doubt the ones on your existing gauges will be exactly the same. You could cut the power wires on your existing ones and connect them to the power wires on the prosports. As for the sender wires you'd have to use the ones supplied with the prosteppers and get yourself a sandwich plate as well if you're getting oil pressure and or oil temp.
