Look in your owners manual if you have it. You can either use the ignition fuse under the hood or you can use the gauge or radio ruse under the dash. The wiring is easy, just buy the tap kit, pull whatever fuse you are going to use, hook the fuse tap kit to the power wire for whatever you are wanting power for, insert this tap kit into the fuse location, reinstall the fuse into that tap kit and make sure there is a fuse in the tap kit for what you are about to power and thats it.
