I'm looking to connect a ford gearbox hall sensor to my ECU, the hall sensor is currently powered by my speedo which supplies +8v as its input; are the pulses from this sensor safe to use as I have read in the WIKI that:

"Protected connection of wheelspeed 1 - suitable for HALL sensor that pulls to GND, or 0/5V or 0/12V signal.

The circuit installed by default (WHEELSPEED_IN=EC18/8) when controller is ordered with PS2=NO (which is the recommended default):"

But everywhere else generally recommends a max of +5v for any wheel speed signal.

My ECU is serial V3.3_u004869

Thanks
