1994 Nissan Pathfinder Radio Problem

My father owns a 1994 Nissan Pathfinder and his factory radio is dying, so he bought a radio on eBay. Here's where it gets interesting. The radio is supposed to work in a 1994 nissan but it's really meant for a 1996 nissan. The wiring isn't the same, so I'm trying to help him out by trying to find a wiring diagram for both the original 1994 factory radio and his new 1996 radio.

Can anyone help?

Please and thank you!
