Hi all, whilst putting my erst engine back together i have noticed that i do not have the green multiplug (the one under the servo vaccuum pipe) on my inlet manifold. there is no hole for it. I have looked on ebay and suchlike and all the escorts seem to have them. Do i need it and if so what does it do. Also i cannot seem to find where the white round multiplug on my wiring loom connects to.
Please help.

Thanks
Graham
