Output voltage, spark out MS3X, for speedo use

Hi,

I've a question about the output voltage of the spk A-H ports, is it 5 V? All other outputs are ground switching and I need a pull-up right?
I would like to use an output for driving a speedo, which usually gets a 5V hall signal.

Thanks
Julian

Yes, spark outputs are 5V low current. As is PT4. All other outputs are ground switching and would need a pullup resistor.
