How to install Fox 302 into SN95 V6?? Please Help!!

My brother wants to purchase an older style 5.0 (87-93) and install it in his 97 3.8 car. I've seen in magazines where people have installed them with the older style intakes. Can the older computer harness and engine harness be plugged/spliced into the newer car? Any websites or information would be greatly appreciated!

Thanks!
Ken
