This swap, as you are finding out, is not a straight up swap.
Not only are the connectors different for some, but what each wire goes to on the PCM is different for some of them as well. So even if you cut the connectors and splice in new ones to fit the sensors, it will not start as signals are not going where they are supposed to go in each case.
You are going to need the wiring harness and the pcm from the 2008 to install into yours in order for this to work and the pcm will need to be flashed with a scan tool and software with your vehicle's vin number for the antitheft system to not disable the fuel injectors.
