Just did this about two weeks ago so it is still fresh in my memory. I have the Rally-4
In the back, you will find a Torx 50 and Torx 55 bolt. I connected the back to both of the seat belt anchor points. You just need to remove the seat portion, the back can stay in place and you should be able to work around it with a 3/8" socket and extension.
On the front, I elevated my seat fully and put the left hand mount on the same Torx bolt as the factory seat belt. The connection next to the tunnel there are two schools of thought. I was able to connect mine to the same location as the factory seat belt using a box-end wrench.
Andy (SVTSTS) connected his to the seat rail so he could further tighten the lap portion by lowering the seat all the way, belting-in, and raising the seat.
Hope this helps.

PS, since you can disconnect the front and back parts
I just wedge the buckle in the back seat. I've installed
my daughters car seat without drama right behind my seat,
even after the Schroth was installed.
