Car Alarms: powerlocks, power locks, actuators

Question
I have a 2000 Focus and I want to install power locks and an alarm. I bought DEI aftermarket actuators but I am totally confused about connection. Do I need a 30 amp relay, a door lock relay module or a door lock interface like DEI 451m? Is this all the same stuff or different applications? What connection should I follow and what relay type do I need to make the right connection. Do I need a relay at all?

Answer
Sorry, I don't do the support for those systems here.

I refer these folks to either my forum
at www.installsupport.com or, I have a
guy at sales@tampacaralarms.com who might be able
to offer some insight. Good guy and he will treat
you right.

Sorry I could'nt be of more service.
