just got done installing my viper 790xv, by myself. it wasnt that hard in my old truck, 1986 silverado. it all works great, but i also added door lock actuators since i didnt have power locks. i think i have them hooked up correctly, but they will not lock/unlock with the alarm. do i need relays for them, or are they supposed to be hooked up directly to the brain? the install book didnt say anything about relays for them
