These little fuses make things so much easier! If you have no wiring experience or if things are just too hard to get to in your car, these are such a great idea. I don't know why I didn't know they existed before! Just use the heat shrink to join the wires and plug and play! Worked great for car alarm, I imagine it would also for dashcam, remote starter etc. Shaves serious time and headache off of the task.
