OK, back up. The problem isn't what you have done wrong, it's what you need to do right.
I strongly suggest you proceed in this order:
1) Repair all the wiring. I mean, get the factory wiring diagram at Nicoclub, then re-connect every wire (using butt splices if necessary, no "twist and tape" allowed...ever,) and do it EXACTLY as it was from the factory. Do not bypass this step, because messed up electrical systems are the doom of Muranos and other modern cars.
2) Pull any codes from the OBDII port. If none, try cranking, then pull codes. If you have to go out and buy a code reader, do so, because you need it for every car you own now and will own in the future.
3) Look up codes using Google and you'll get a clue as to what's wrong. It probably won't give you exact info, but if you get a bunch of sensor warnings or other related warnings, it will give you direction.
Come back and tell us what you learned.
