ok so i just installed a bmw nitro alarm this one
http://compare.ebay.com/like/1206807...=263602_304662
and it works great and i ordered this 2 wire door actuator
now on the wiring diagram for the alarm it has 2 wires for the door actuators
so im wondering if the relay is built in or not and if not how do i wire them up? this was my first alarm install and i have searched so i just wanna know before the actuator gets here. thanks in advance this is the door actuator

You will need relays, [two (2) SPDT relays] the two leads out of the alarm that are for door locks, [probably green and blue] are low current grounds, you will yous them to control the relays, wire like this, Actuators/Reversing Polarity... http://www.the12volt.com/doorlocks/page3.asp#arp

This is a pretty good read also... http://www.the12volt.com/relays/relays.asp 94

 

thank you for the quick reply.
funny because i was just reading someone elses post sort of like mine and you helped them out. and the lock out put is green/black negative and the unlock output is blue/black idk if that makes a difference. thanks again though

 

The most common colors for low current door lock outputs is green and blue but it is not universal, because there are only 2 leads for the door locks they can only be low current outputs, the color, [black tracer] will not make a diff. 94
