I've completed the swap and I had to swap the wire harness under the intake manifold that goes to the fuel injectors and etc from the old engine onto the new one. If I used the 2005 harness it wouldn't attach because the plug is too big and on the wrong side of the engine. The van won't start and I don't know what to do. It has new spark plugs and the firing order is correct. I pulled one wire of and attached an old spark plug to it and it fires once and then quits firing. I've searched and can't find a solution. Oh both are 3.3 engines. Thanks.

 

You're going to have to use original injector wiring AND injectors from the 2002. As for the other sensors, I think the cam and crank have different connectors, but are wired the same.

 

cool, how do I know what to cut and spice to get the wires to match up? The cam and crank sensor are the same I checked them with the local parts store. Thanks.
