[Plugin: Pronamic Google Maps] Custom Google Map Embed

Hello: First let me thank you for a much needed plugin.

I have a custom Google map (I drew a shape for a service area). I need to know how to use the plugin to embed on a wordpress page.

This is the google maps link code:

<iframe width=”425″ height=”350″ frameborder=”0″ scrolling=”no” marginheight=”0″ marginwidth=”0″ src=”https://maps.google.com/maps/ms?t=m&vpsrc=6&msa=0&msid=201348758476905368337.0004b648e0f413aa833be&source=embed&ie=UTF8&ll=37.749001,-121.168213&spn=1.520188,2.334595&z=8&output=embed”></iframe&gt;
<small>View American Lock and Key Service Area in a larger map</small>

This is the map URL:

https://maps.google.com/maps/ms?msid=201348758476905368337.0004b648e0f413aa833be&msa=0&ll=37.935533,-121.313782&spn=1.865071,4.22699

The plugin page gives some php coding and I have no idea what to do with that or where to put it and then what short codes to use.

I am a novice and all simple help is greatly appreciated!
