You could call any vendor that sells them for the instructions, or contact any shop that installs them and see if anyone wants to help.
A little help from either of those could lead to a customer, and the good companies know that.
Start by removing the carpeting from the trunk on the passenger side, that's where you'll make your connections.
Chances are, you have +/- to the battery, those pigtails hook into the stock FPM (or whatever they call it) and maybe there is some sort of boost reference or something.
I think
@Speedy! made a video of the install, so youtube and google should help a bit too.
