The Molex 1727670016 is a 16-circuit, 2-row plug housing from the Mini-Fit TPA2 172767 series. The housing is designed for panel-mount, snap-in installation — it clips into a panel cutout and the locking ramp holds the mated pair secure against vibration. This is the plug half; it mates with the matching Mini-Fit TPA2 receptacle housing.
The one thing that trips people up: contacts not included
This is a housing only — the male pin crimp terminals are ordered separately. The most common sourcing mistake on this part is assuming the contacts come with the housing. You need the matching crimp terminals (Molex Mini-Fit TPA2 male pin, 20-24 AWG) to populate the 16 positions. The housing accepts the terminals after crimping, and the TPA (Terminal Position Assurance) feature in the TPA2 series locks each terminal in place so a partially seated contact doesn't leave the harness dead.
