So are you trying to add some power door locks?
How will this tie into car computing?
You did not list a model of controller or linear actuator, but I would assume yes.
If this is not carpc based and more of a general auto electric questions you may have more luck searching a forum specific to your car model.
For example I drive a 06 lan evo ix, if I have trouble with my pc sound card I come here, if I want to install a power truck release im going to go over to evolutionm forums.
