Please take a peek at this thread and many of the other threads found in the same section you posted this thread in: http://www.ranger-forums.com/f102/bo...vaganza-83805/
It's packed full of very useful info. The kit you get covers all bases in regards to wiring, brake lines, etc. In the link above, take a look at the downloadable instructions. I went through those probably a dozen times learning before I even turned one wrench. The instructions also cover the shift extention and yes it does literally go between the trans and the stock shift arm.
Note: For your '09, you're going to have to order 2 extra blocks and bolts for your bed. '09+ shortbeds have 10 bed bolts where earlier models only had 6. Kits come with 8 blocks and bolts to cover the longbed models, so you'll be 2 bolts/blocks short. You can buy blocks straight from Performance Accessories for about $3 each and bolts about the same price. Don't forget those thick bed washers too. I do not know if that sticky thread has this info in it yet or not, but I'll find out and try to have it updated.
