This Mini ATM fuse holder is usually used in conjunction with a blade style fuse tap and is included with the AutoPilot V2, Air Lift Performance 3P, and Air Lift Performance 3H systems. If you are trying to replace your ignition wire fuse holder and this doesn't look like what's currently in your car, you may be looking for an Add-A-Circuit. Be sure to purchase the proper amperage Mini ATM Fuse for your needs.
