So I go camping in my Prius time to time and I hate I can not open the back trunk from the inside. So I installed a quick release button. I saw a write up and a youtube video for 3rd Gen but nothing for the 2nd Gen work horse. Here is my how to write up.

So I bought a cheap ebay horn switch or momentary on switch.
Connect one end of the switch to red wire found under trunk trim. Check photo for location.

Then the ground end from switch to the white wire on lead wire in trunk release lead.
Make sure you attach connectors between the switch and original wire leads in trunk. This will allow you to pull the trunk trim if you need to do other work. Also the trim panel won't be permanently attached to trunk hatch.

The yellow horn switch uses a 3/8 drill bit. I drilled a hole by the trunk handle shown in photos. Connect all the wires and close up trim panels.

Now you have a quick release inside if you sleep in the Prius when camping. No more exiting from the side doors.
Smash if you like it!!!!

I'm learning how to use this site.
I just realized you've tapes into the switch loop/in residential talk/ I've got to try this!!!!!!!!! If it works.My idea is to install a keyed lock/switch so I can open from outside.
