Wiring wise it will fit but the pipes will be different so you'll either need the pipes from a 4x4 or you'll have to make new ones.
The 4x4 pump motor also sits closer towards the exhaust manifold. I have an extension piece between the 2 sections on my 2wd manifold due to running a GT30 so this brought the manifold VERY close to the motor so changed my 4x4 pump to a 2wd one. You should be fine if using a normal 2wd manifold with no extension piece.
