Hello and welcome to JustAnswer!

You wouldn't use a wiring harness that came with a used engine. You'd want to remove the harness from it as well as any components with a different electrical connector. When removing the original engine the wiring wouldn't be removed from the engine compartment, just the engine.

The tone wheels can be swapped but it's labor intensive and if you bought the engine from a junkyard they may not honor a warranty if they found out you did such a deep repair/modification. The tone wheels can be swapped but to do the crank tone wheel you have to remove the bedplate from the block and completely remove the crank from the engine.

Doesnt answer my question about what to do about different connectors 2006 has a 4 plufg and 2003 has a 3 plug, how do I solve that. WITHOUT BEING CHARGED AGAIN BECAUSE IT WAS ALREADY ASKED AND NOT ANSWERED.

I did address that in my first paragraph but maybe you missed it. You can't use the wiring that came with the incorrect engine, it's for a completely different control system. You're replacing the engine itself, not the wiring harness.
