Yes, they come with a oil pressure sender and temp sender. The fuel gauge can be programmed to your existing sender and the volt gauge just needs power. The tach goes to negative of coil and the speedo uses its own GPS signal so nothing goes to the trans. I don't have any pics of the wiring to the vehicle but it's all just wire-to-wire at the old cluster connector. The gauges come with in-line connectors so it can be removed.
