Up grading my fuel injectors...

So I recently purchased a 4.0 throttle body, electric fans, and new fuel injectors for my 1993 2.5L. The throttle body seems easy enough to change out and the fans seem pretty straight forward. I've tried Youtube but didn't come across any videos for a YJ...but plenty for the XJ. Is it a pretty simple process? And are there going to be any possible unforseen issues that maybe someone else on here has delt with? Any help would be greatly appreciated before i start taking things apart.

Lol well that sounds reassuring
