My only interrogation is that once the JB3 ctrl box is slided inside the ECU box, it seem impossible to 100% seal the ECU box after because of the JB harness going out. It seem mostly sealed, I only hope water wont go inside the ECU box, where the harness is going out.
any one can help me with this? Can I put the ctrl box outside the sealed ECU box?
