JR-style connectors are the standard 3-pin servo plug used across most radio gear, and this set lets you make up custom-length servo leads, extensions and Y-harnesses, or repair a damaged plug without replacing the whole lead. The 2.54mm pitch housings accept one signal, one positive and one negative contact, and are keyed so they only seat one way in the receiver.

Contacts supply loose on carrier strips and crimp to your wire, then push into the housing until they latch. A crimping tool is recommended for a reliable joint — we recommend this Crimping Tool for these connectors. Soldering the contact after crimping is optional but helps on stranded wire, heat shrink is not included.
