Universal ISO Extension with 12v Switch and Current Blocking Diode CT51-UV01

The CT51UV01 is a universal ISO extension harness with a built-in rocker switch. This ISO harness is ideal when installing an aftermarket radio into vehicles that feature a 12V permanent feed within the radio harness.

The CT51UV01 allows you to manually switch on the radio without having the vehicle's ignition on. A perfect accessory for camper vans and motor homes, this harness allows you to listen to the radio when parked without having to have the ignition on or the engine running.

Note: Running the radio without the engine to charge the battery by the alternator or running or an external battery charger will discharge the battery. The switch housing needs a 20mm hole to fit and a minimum mounting depth of 38mm.
