Aptiv 12089040-L Loose Male Wire Terminal Tin Plated

12089040-L is an Aptiv (formerly Delphi) Weather Pack male terminal, sold as a loose-piece version (-L) for 20-18 AWG automotive wire, or 0.50–0.80 mm². The contact is tin-plated and built around a tin-brass body to resist corrosion while maintaining solid electrical contact in harsh automotive environments; it crimps to the conductor at an inner-seat and forms the cable-seal at an outer-seat, with stamping designed for use with T-18 or 12014254 crimp tools and a maximum current rating of 20 A. The -L suffix denotes loose-piece packaging and does not change fit or function versus the standard part, a detail documented by distributor listings that note the “L” variant is the loose-piece version (no difference in performance). It is commonly used in automotive wiring harnesses that require Weather Pack sealed pin connections and is listed in Aptiv/Delphi Weather Pack catalogs for 18–20 AWG conductors.
