i am trying to do a keyless entry from scratch, i have the actuators and bothe the lock and unlock wires need to be grounded and then the alarm put off a positive charge to move the actuator, the problem i am having is a way to ground both wires and when i press lock or unlock that the power dosnt also go to the unlock, if i have only one ground hooked up it will lock or unlock depending on what side i have grounded but when i ground out the other wire it quits working i think what i need is a way to isolate the ground so they dont back up to each other

Actuators / Reverse Polarity

This is practically identical to the 5 wire alternating 12V(+) system above. The only difference is there's no switch! Both motor legs rest at ground at the relays. To lock or unlock the vehicle, polarity is changed on one motor leg.
