See Digikey part number WM9591-ND. The pigtail is inserted into the hole in the slot to enable wires to be connected to the PWB on the inside cavity of the back of the housing. I need to add a drawing of the part but have not been able to find a 3-D of the part online.</div><div id="yiv3338928686yui_3_16_0_1_1442186736151_3743"><br clear="none"></div><div id="yui_3_16_0_1_1442203408289_3584">cliff</div></div><div class="yiv3338928686gmail_extra" id="yiv3338928686yui_3_16_0_1_1442186736151_3744"><br clear="none"><div class="yiv3338928686qtdSeparateBR" id="yui_3_16_0_1_1442203408289_3585"><br clear="none"><br clear="none"></div><div class="yiv3338928686yqt4734624578" id="yiv3338928686yqtfd69286"><div class="yiv3338928686gmail_quote" id="yiv3338928686yui_3_16_0_1_1442186736151_3747">On Sun, Sep 13, 2015 at 7:26 AM, Alec Smyth via Personal_Submersibles <span dir="ltr" id="yiv3338928686yui_3_16_0_1_1442186736151_3746"><<a rel="nofollow" shape="rect" id="yiv3338928686yui_3_16_0_1_1442186736151_3745" ymailto="mailto:personal_submersibles@psubs.org" target="_blank" href="mailto:personal_submersibles@psubs.org">personal_submersibles@psubs.org</a>></span> wrote:<br clear="none"><blockquote class="yiv3338928686gmail_quote" id="yiv3338928686yui_3_16_0_1_1442186736151_3749" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;"><div dir="ltr" id="yiv3338928686yui_3_16_0_1_1442186736151_3782">Wow!!!!
