OBD2 Y-splitter leads that let two devices share one diagnostic socket, or feed a scan tool and a data logger at the same time. Configurations include 1-to-2 male-to-dual-female, 1-to-2 male-to-male-plus-female, and 1-to-3 builds with 16-pin J1962 ends.
Wiring is straight-through on all 16 pins unless you specify a split map; 22–24 AWG copper with foil shielding keeps data lines clean. Low-profile right-angle shells fit tight under-dash spaces. Custom pin splits and lengths from 100 pcs, samples in 5–7 days, production 20–25 days.
