5 watt solar panel

I'm pretty sure we have the same panel. If so, it is mounted to the top of the front air conditioner shroud. There should be a "quick" disconnect wire harness right at the panel itself. On ours, the wire had exposed some and corroded out. I had to cut apart the rubber of the harness since there was not a lot of slack to the wire then cut the wire behind the existing connectors then just stripped and crimped new blade connectors on.

All this was of course after I took my cheap multimeter up and verified that the panel was still putting out voltage.
