avital 4103 unlock/lock not working

Thank you for your help. I have looked at the 12volt site and found a 5 wire reverse polarity diagram and used it. Grounded the wires. It works and 5 wire relay you gave me doest work. Im not sure why. Could a bad switch cause the problem on the car  itself?

This is how I did it.

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.
