Line 4:
Molex KK ''housings'' mate with Molex KK ''headers'' on the [[PCB]]. The metal sleeves inside the housing are secured by [[crimping]] each conductor in two places, on the wire and on its insulator. A ''gas-tight'' connection is created between the wire and sleeve, prohibiting corrosion and a the crimp on the insulation creates a strain relief, providing additional resistance to mechanical stress.<ref>Molex Connectors Explained, as used in Pinball.

The Molex headers look very similar to the [[MTA Connector]] ones by TE AMP, but they are not the same. Do not try an force a Molex KK housing onto a MTA header or vice versa.<ref name="oakley">Oakley Sound Systems, [http://www.oakleysound.com/construct.pdf Construction Guide] by Tony Allgood, v1.2.4, 24th September 2013, p. 27</ref>
The housing and metal crimp terminals are bought separately. Generally two different sizes are in use, 0.1” (2.54mm) for signal connections and 0.156" (3.96mm) for power distribution. For 0.100" use wire of 22, 24, 26, 28 or 30 [[AWG]] with a maximum diameter of 1.57mm.<ref>Molex data sheet [http://www.molex.com/webdocs/datasheets/pdf/en-us/0008500114_CRIMP_TERMINALS.pdf 08-50-0114]</ref> For 0.156" use wire of 18, 20, 22 or 24 AWG, with a maximum diameter of 2.79mm.<ref>Molex data sheet [http://www.molex.com/webdocs/datasheets/pdf/en-us/0008520072_CRIMP_TERMINALS.pdf 08-52-0072]</ref>
