as far as the full throttle shift, launch limiter, etc, do you give it a ground or + 12v?

Good question. It depends on the input:
ACS, PSP, SCS, VTP go to ground. BKSW goes to +12V.

so bksw is the only 12v? excuse my ignorance, i am new to this system. i assume when it says invert input, that means you can change it from a 12v to a ground input and vis-versa(sp)?

Inverting only means that on is an open connection and when you invert it you change that to be off when the connection is open.

No, invert input will swap the state of the input (on or off). The input still be either be switched to ground to +12V.

so power steering is ground?i hooked it up that way today and it doesn't work.

i hooked it to the a/c input and it worked.i still need to know about the p/s though.i am going to hook the fullthrottle shift to another output and wanted to use it. could it be that the ecu i am using had no input for it?if so,i could use another input

What ecu are you using?

it's a p28.i just used a different input and it worked
