What This MCON Plug Housing Is
It uses a 4.00 mm pitch, carries a tab-style contact interface, and is terminated via crimp — meaning you supply the terminals separately.
Sealed Housing, Contacts Not Included
The housing carries a sealed feature, which means the mating interface is designed to keep moisture and dust out when paired with the correct sealed receptacle and sealed terminals — typical for engine-bay or underbody harness runs. The note on this part is straightforward: contacts are not included. You order the 2-1703498-1 housing separately, then source the matching MCON tab terminals (sized for your wire gauge) and the receptacle housing with its own seals.
