Trying to install bed led lights connecting to the wiring harness on driver rear side. Cannot find anywhere.

Which wiring harness? The one to the driver's side tail lights? Use a 12V test light. About 15 bucks at a parts store. I suspect you want the lights on when the tail lights are on, right? Turn on headlights and probe each wire going to the harness. When the probe lights up, you found power.
