Welcome to the LOC. Rather than screw around with jumping wires, drive over to Auto Zone or any auto parts and borrow their code reader (and code clearer) for free. I've jumped wires before with unfavorable results so frying some obscure electronic component isn't out of the question. I finally just bought a cheap ($100) code reader/clearer and keep it in my car kit.

Another way is to just disconnect the battery for awhile.
