Pink/Purple is 8720 plug, which the 50i uses. I'm not sure which one the 35i uses, but if it's too long, then I guess all US cars use the same 8720 plug.
The red one (4720) has very long connecters which is what does not allow the pins to touch and not have a proper clicked connection; thus, this leads to no sensors being plugged correctly leading to Low power mode aka Drivetrain Malfunction (drive moderately).
