To my knowledge the 6 pin 750 power connector:
1 = Ground
2= +12 V in
3= Relay on (it gives ground to a relay which is used to power up external stuff like ez-steer, field-iq etc. when the 750 display is on).
4= Ignition Switch (I have not used this, I guess it will turn the display on when it gets +12V ???)
5 and 6= can lo/hi (but on my 750 this did not work, so I use can hi/lo from 12 pin ports A and B)
