I wanted to ask if when using voltage sense, there is no physical wire that needs to be hooked up as it is something that is featured in your remote? Where as with tach, there is a physical wire? Any help would be appreciated...thank you.

Most systems will 'read' voltage sensing off of the wires connected to the ignition wiring in the vehicle without requiring any additional connections.

Tachometer connections require a physical connection, and are normally the most reliable method.

Installer, IT support, and FFL. I need less hobbies.
