I picked up one from Tone while in Moab. It came with the same direction you all probably got. Yes, it doesn't say much, cause there isn't much to say. It explains all that needs be.
Only problem you should have is finding the correct plug to connect it to. Then route your power cable up through your engine bay(as others have done) and hook it into the fuse box to your fuel pump. Now just follow the instructions that say put adjustment for pressure lines to half way and adjust from there....if you don't have a pressure guage. Next, do the same with torque convertor delay.......then adjust from there.
Doesn't take long at all....unless you have a diamond plate skid plate, then it is better to remove it, but not necessary unless you have big hands like mine, then it was totally necessary.
I didn't have a problem with getting it connected, no pinched nerves, etc... just finesse it.....or find some neighborhood kid running around and pay em to do it for ya;Dp; .
A few adjustments was all it took for me to get it where I liked it. I mounted mine to the frame in such a fashion as to where it would be easy for me to turn it to the side, adjust, then turn it back against the frame. If you do this make sure you have cables lifted away from exhaust or they will sag and get scorched.
Now, that I have mine adjusted where I want, I can remove it from the frame and mount it permently up and away from frame and exhaust, so as not to ever worry about it being exposed or scorched by exhaust.
