Termination and wire fit
The 140971-2 is a male quick-disconnect tab from the Faston, PIDG series, accepting 13-17 AWG wire with a crimp termination — the serrated termination bites into the conductor strands for a gas-tight joint that holds up under vibration. Non-mating end insulation in blue covers the crimp barrel and part of the wire, so the exposed metal is only the 0.250" (6.35mm) tab that mates with the receptacle.
