1984 2.3 turbo

I have a 1984 Mustang 2.3 L Turbo. Like just about everyone else, I always want "just a little more power..." So, I found an intercooler and purchased it. But that's all I got- I am wondering if there is a list of needed parts and installation instructions that were typed slowly, using single syllable words somewhere. I tend to be a little slow, and would like to get the install done correctly... Thanks!
 
What's the intercooler from? Aftermarket or?
Be aware an I/C is more effective when your power level is raised by other means. Typically, headwork, bigger turbo, full 3" exhaust, etc. Give us a little more info on what you have.
