I know that someone is going to laugh at this, but how do I change over my gauges to the electrical type. Currently all my after market gauges are the mechanical type, ie they have a tube (Normally copper) coming from the back of the gauge and going to a sensor/adaptor attached to wherever it should be. I would like to change over to some smoke face gauges but they only come in the electrical type, and all they have is a bunch of wires coming from the back? Anyone got any ideas?
