I got started on replacing my OE speakers starting with the 3-1/2" dash speakers. My Limited has a non-JBL system making this easier. I purchased Infinity Reference-3022cfx. I did not want to cut up the factory harness so I searched for anything that would work. I found that a harness for a 2017 Camry-non-JBL will work and is sold by TacoTunes. Part #77-EZSH04-02B . The connector fits with 36" of wire that you still have to put wires in parallel with the cap in series on the positive wire. I shortened the wires by a lot and crimped the ends with connectors to the new speakers. This way, if I decide to put back the OE speakers--no damage done. The wire harness pair is approx $24. Sorry about not having pics to show you.
