You will need a new transmission range switch. People break them all the time, the factory uses a sealant almost like a glue on them to keep them weather tight. A little time with a heat gun and they come apart super nice, if there's a pick a part near might try that vs a new one. If you want your EMC to control the trans I'm pretty sure you need those two connectors as well as the main valve body harness on the other side. Doubtful a parts store will have ECM pins, that's an online thing or the junk yard, or dealer. The oil level sensor I would leave deleted. The rear o2's, even with cats do nothing for fuel trims, they are souly there to keep tabs on the converters, you can add them if you want, but not necessary for operation.
