Don't go unprotected!

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 that provides both constant and ignition hot circuits. No more tapping into an existing wire or into a spare circuit at the fuse block. Using these add-on, relay activated fuse blocks is the safe way.

Only a small activation wire from any ignition source is needed to turn on the relay that turns on the fuse block. All CirKit Boss models are made using TXL cross link polyethylene wire rated to 275° @ 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, & terminals. Protects your O.E.M. warranty. Easy to install. Safely adds ignition hot and constant hot circuits.
