[RB200sx]

I'm not too familiar with the newer Ravs but it shouldn't be too hard. The wire harness up to the connector should already have the wire in the harness. A service manual should help in determining that.The only thing would be to replace the switch with the optional switch and install the fuse and/or relays that will make it work for that circuit. Your owners manual has a fuse and relay page. That will tell you where the fuses and/or relays should be, assuming the circuit is there. Oh, before I forget. Don't confuse the owners manual with a service manual. A service manual will have a more detailed schematic of the wires and the related connectors such as the one you're trying to put together. The service manual for your Rav is not cheap, though, and you can order one through the dealer if you want. The book for my wifes' 04 Sienna is about $150.00. Again, not cheap but it's a real good source of repair info that you wouldn't get other wise. I have to get the book for my 97 Rav. I have one for my 87 200sx. I got that one for $74.00 back in 2000 and that's only because the car isn't manufactured in that particular body style any more. Other wise it would have cost as much as the one for my wifes' Sienna.
