The 8" Pocket Wizard Polarity Reversing Cable Adapter MMRP has a 3.5mm female and male connection that plugs into any Pocket Wizard radio. Meanwhile, you connect a compatible sync cord to the adapter cable, and if you experience any polarity symptoms such as your flash no longer fires or the radio's red LED stays on; then, this cable corrects and reverses it to an industry-standard polarity.
