+==== Important Note: Vehicle Speed Sensor ====
+The Holley Terminator X and HP EFI do not have a way that I've seen of accepting a speed sensor signal. To workaround this and still send a speed signal to your speedometer without upgrading to a Terminator X Max or Dominator there are two options most people have done:\\
+You could keep your stock ECU wired into power, ground, ignition voltage, and the speed sensor and use the stock PCM just to convert the VSS sensor signal into a signal for your speedometer. Extend those wires and hide the PCM anywhere you want to.\\
+You could also use a [[https://sirhclabs.com/product/vr-to-hall-sensor-converter/|VR to Hall sensor converter]] box according to some posts on the internet.
