The Contacts Are the Catch
For the Mini-Fit TPA2 series, the mating terminal is the 45750-series crimp pin, which takes 18-24 AWG wire. The crimp height and pull-force spec live on that terminal's datasheet, not on this housing. If you are building a harness, section a sample crimp and count the strands captured; the wrong die or an under-crimped barrel is where field failures start.
This plug mates with the Mini-Fit TPA2 receptacle housing — the 172763 series — which accepts female crimp terminals. Both halves use the same 4.20 mm pitch and dual-row layout, so the 12 circuits line up one-to-one. There is no secondary keying beyond the housing shape, so confirm the receptacle order code matches the circuit count before you commit the assembly.
