Painless Performance CirKit Boss Auxiliary Fuse Blocks provide you with the protection you need! Electrical accessories can send voltage spikes through your system, damaging everything from light bulbs to diagnostic computers. The safe way to add electrical accessories is with the Painless CirKit Boss, the first circuit isolator containing both constant and ignition hot circuits. No more tapping into an existing wire or a spare circuit at the fuse block. Using an add-on, relay-activated fuse block is the safe way.
Only a small activation wire from any ignition source is needed to power the relay that turns on the fuse block. All CirKit Boss models are made using TXL cross-link polyethylene wire rated to 275 degrees F at 600 volts. All wires are factory machine terminated. Circuits are individually fused for up to 20 amp applications. CirKit Boss includes an in-line circuit breaker, relay, mounting hardware, and terminals.
