4L V6 engine swap

I have a 4L engine from a 92 Explorer. I would like to use it to replace the 4L engine in my 94 Mazda B4000 which has over 200K miles and is pretty tired (not to mention bad cam sensor, leaking head gasket, etc). Does anyone know if a 92 engine is compatible with a 94 chassis/wiring? Also, the Explorer engine had an automatic trans and the Mazda has a 5sp manual. Will they mate up?
Thank you.
