I did not. I just did a simple vertices pull wire to place a knob or something at the top of the rear door like everyone else. For now I have a loop of paracord back there until I find a knob I like. Might just leave it there. It's quiet and strong. I have 4 kids, my son likes sitting back there and uses it all the time. Also while camping - we sleep inside.I know this is an old thread but I’m hoping to do something similar. Im very curious, did you ever end up successfully installing that recliner latch?
These pics show where I have wire and holes drilled. I actually had to drill a home through the rear door sheet metal in order to get a drill bit at the right angle to drill through the door mechanism lever.
If you need more pics let me know. To install any of the other handles would involve a lot more work and modifications that wasn't worth it to me unfortunately. Would make it look clean like a prado though.
To connect to the door mechanism unused wire, them looped it and connected the doubled paracord loop through it.
