I've just looped it up over the lip... I'm reluctant to do any cutting on it, since it's there to keep water out... :shocked:
This Winter; I might try something involving a cut-out, a grommet, and lots of goop to seal things up.
By looping it over the lip, you just did allow water to get in by compromising the rubber seal of the lid

I think the easy and simple way is to drill a hole, run the cable, then just use some silicon sealant from Home Depot and seal it off. If you ever need to remove it, it is easy to peal the sealant away.
