My bet that is since its a 94' 2.2 the sensors will be pretty much the same and the 1.8 harness will just plug right in. Only thing i cant think of off hand is the Ex. manifold. Is the 2.2 a single exh port per head? cause the 1.8 is dual. Means you might need a 2.2 exhaust manifold. It sounds like a very easy swap.
