PolarStar Airsoft Wire Harness Rev. 2

The PolarStar Wire Harness is designed to provide reliable power delivery and long-term durability for PolarStar electro-pneumatic HPA systems. Constructed using 24 AWG wire, it offers strong electrical continuity to ensure consistent engine and FCU operation during use. To protect the wiring as it passes through the replica’s body, the harness is wrapped in a nylon mesh sheath. This helps prevent abrasion and damage during installation or regular gameplay, particularly in tight gearbox and receiver spaces. The harness is universally compatible with all PolarStar electro-pneumatic HPA systems that use a REV2 or REV3 FCU, excluding the original V2 GEN1 Fusion Engine and Amoeba kits. Multiple lengths are available to suit different gearbox types and installation layouts. Read the full description for the harness length guide.
