PolarStar Wire Harness Rev. 2 – 18″
The PolarStar Wire Harness Rev. 2 in 18″ is the current-revision electronics harness for PolarStar HPA engine builds. PolarStar engines (F1, F2, JACK) use electronic trigger control — the wire harness routes signal and power between the battery, trigger contacts, solenoid valve, and any ancillary electronics in the build. The 18″ length suits longer routing paths in full-length rifle builds — AEGs with longer runs between the gearbox position and the battery compartment, or builds where the harness needs to route through a stock or upper receiver before reaching the engine.
Rev. 2 is the current revised harness specification for PolarStar engines. For PolarStar engine operators requiring a replacement wire harness, or builders assembling a new PolarStar HPA conversion, this is the Rev. 2 specification in 18″ length. Verify connector compatibility with your specific PolarStar engine model before ordering.
