The Molex 1727670016 is a 16-circuit, 2-row plug housing from the Mini-Fit TPA2 172767 series.
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.
