I am doing a RHD conversion on a 03 EP. Got a JDM front clip minus the engine and tranny. Everything has been swapped over including RHD dash with JDM wiring harness. I am using the stock USDM engine wiring harness and ECM. Will the US engines harness th the JDM dash harness? All plugs have a corresponding match with the exception of the evap system. Car will crank, but I have no spark and appears the injectors are not firing. I have checked all grounds in the engine bay and under the dash.

Can anyone tell me if a JDM EP3 TypeR dash harness will work with a USDM engine harness and ECM? Is the ECM pinout different?
