I did this as well. Got a switch that fits my DD '98 Ranger from Autozone. Found it didn't come with the pigtail so I went to the salvage yard and picked one up. You could just get the pigtail and switch from the salvage yard as well. You can also use it as a hidden kill switch if you want. There's a little slot that a key or something slim that will fit through under the reset button to trip it.
