motor swapped maybe?

i think the motor in my 95 hardbody was swapped out for a 94 motor does anyone know if all of the smog stuff is in the same spot or what?because i have tons of extra plugs and not alot of it is matching up. any help would be great.

those are probably the extra stuff most Nissan's don't run like power steering a/c cruise and every truck is wired for everything they just don't all have everything if that makes since

THE TRUCK HAS P/S A/C THE MOTOR LOOKS LIKE ITS BEEN SWAPED OUT OF A DIFFERENT YEAR THERE IS 3 DIFFERENT SENSORS ON THE INTAKE MANIFOLD THAT DONT HAVE A BUDDY A PIC OF A 95 WITHOUT THE AIR CLEANER ON IT MIGHT HELP ME THIS TRUCK HITS ITS REV LIMITER @ 3000 RPM ANY HELP WOULD BE APRICIATED

i fixed the prob there was a loose mas air flow sensor (it was plugged in just not clicked in all the way)
