Hi! I want to wire a small trailer to my 1997 RAV4 electrical system.  
  
 Where can I make the connections?  
  
 Thanks! Bernie

In the back where the trailer hooks up. Sorry but I couldn’t help myself.

Go to a auto parts store and find out if there is a adapter that will just plug into the wiring harness. I believe the brand name of these adapters is HOPPY.

First check-out if there is a factory harness that you can add to the existing harness.

Then see if there is a aftermarket harness offered.

Bernie, It Looks Like A Plug-In Is Available For Your 97 Rav4 !  
That would be the easiest, best way to go.

Thanks! I was going to push the trailer. But you were right about the HOPPY plug-in  
wiring kit which is available for the RAV4. Bernie
