yes all your wires will still work. there are a couple pigtails that need to be extended due to placement of components on the engine but all the same. even the coolant hoses are similar and P/S pump and alternator. only thing you need to invest in is a new upper radiator hose and the KL31 ecu. it will run on the K8 ecu just fine with a CEL. but the real power comes when you invest in a proper programmed ecu. if you have questions i am more then happy to help a fellow ZE investor
