The Infinitybox Splice Saver Kit gives you an easy way to connect multiple accessories to a single POWERCELL output. Examples include powering your ECU, gauge power, stereo power and A/C power from a single ignition output. Other examples include lighting, locks and stereo power. You can power 5 separate wires from a single input wire. The internal buss bar can be split to create two separate circuits, each with a single input and two outputs.
