#11857, "RE: power lock motor placement" In response to In response to 2
you can run both actuators off one relay.
But to be on the safe after it's all installed, (with actuators under load) lock and unlock a ton of times and see if the relay gets warm. If it gets warm at all I would advise using 2 relays.
I'm a novice listen to what I say and make your own conclusion.
