I am currently in the process of building my first wiring harness for a engine swap project.


Unfortunately i cannot physically mount the engine in the car yet - but i want to finish as much as possible before i rent a space to do the swap.


I plan to locate the ECU/PDM under the dashboard Firewall Passenger Seat. Can anyone recommend me a cable length from ECU to Cranksensor. The Cranksensor on my Swap-Engine is the first sensor closest to the firewall - right behind the transmission adapter - approximately 10cm away from the firewall. And approximately same height as the stock fa20 clutch cylinder - I would measure all the other cable lengths from there.


But how long should the cable be form ECU to Cransensor? - where did you drill a whole through the firewall?


I understand that this question is a rough estimate - pictures of your cable routing would be highly appreciated too...


Maybe sbd has some recommendations...


Best regards
