To do the swap properly you will need a VX ECU P07, it will also be best to get the VX engine harness but you will still need to do some additional wiring, the VX has a 4th plug on the pass side shock tower which has the wires for the 5-wire O2 and the EGR...there is also an additional plug for the EGR control box which is mounted on the firewall in the VX...check out my build thread there are some links and info in there that might help you out, feel free to ask any questions...Matt
