How difficult is it to pull the back seat out of a prime?

Id like to gain access to my prime's battery charger. Is that difficult?

 

Iv invented a specific adapter that fits between a 3rd party 2-way long-range remote start system, and the Prius Prime. It's an electronic device that enhances the remote start feature set. It allows for full-take-over, in other words, no shut down on door open or brake press, just get into a remote started car and drive off. It also allows 2 remote start modes while still plugged in taking a charge at level 1 or level 2. My prototype has a simple manual switch to pick which of 3 modes:

1. normal not plugged in remote start
2. normal mode remote start while plugged in
3. factory remote start while plugged in, but using the 3rd party 2 way remote.

I need to tap into the 120vac/240vac lines to install a small dc converter so while plugged in my device will automatically know what mode to use.

each mode has advantages and disadvantages based on what works best for your situation.

And yes, anti-car theft is still maintained while remote started, fully.

My hopes are to sell the patent to an interested company after a demo that it really works. As far as I can tell, there is no other way to do these things with any other product.
