I'm using the Casper engine harness made for the ECU-GN and the direct coilpack adapter for the d599a truck coil. Can I use the fuel pressure sensor and adapter harness from my old XFI set up with the ECU-GN? The direct coilpack adapter and fuel pressure harness both use the old EGR connector but it looks like they are not using the same terminals in the connector. Can I just combine the two into one connector and plug into the EGR connector in the new harness? If so, what do I need to do to set both up in the software?
