(we've searched the forum, but haven't found answers that we could understand and/or make work)
This latch we're triggering also has a 'signal' line which is connected to a switch that engages when the latch is triggered that we wanted to send that to the dash board so the drive team could tell when the latch had engaged.
Thanks!

You're going to need to know what voltage the signal on the latch needs to be, ie. +5vdc or +12vdc.
Next you will need to determine if the GPIO pins can provide it.
If the GPIO can not, then you may need to develop a driver that will take the output of the GPIO pins and covert it to the needed voltage/power the latch will need.
