relays wiring for linear actuators

Iam using a single pulse from alarm to run actuators up or down. I would like to have a momentary input to constant output so it stays on untill the switch is made. I tried the wiring for this from the wiring diagram section but it didn't work. The wiring of the relays worked but the actuator didn't becouse there are two power wires, when one is in use the other is used for ground. Iam not sure how to make this happen. I could use some help with this.  Thanks Charlie

Easiest way is to use 2 x aux outputs set as timed, the relays just carry the power, same diagram as "adding an actuator" in the relay section. If you don't have two timed aux outlets, you could use 2 x 528t timer relays or similar.

Here's a modified from mirror fold diagram using a pair of 528t's,thus you can use either the lock or unlock (-) signal or a pair of momentary (pulse) aux outputs. If you don't have an existing switch take take each orange wire (on the right) to ground.

It might help if I post the diagram. copy_of_mirror_fold.bmp

Iam using door trigger switches to open and close the 12v power to the relays and I have split the one neg. pulse from the alarm. The actuators are to open and close the trunk.Will the 528t relays you suggested be timed to stay on till the power is shut off? I would like to know before I by them.   Thanks for your help Charlie

Yes they are 20 amp timer relays.

I got the 528t relays and hooked them up like the diagram showed. I might have something wrong becouse it's not working. On the actuators there are two wires one for up and one for down. When power is aplied to one the other wire is used for ground for the motor. Do I have to change something for this to happen? Or add another relay?    thanks Charlie

Take another look at the diagram.

Howie, you were right I didn't have one of the wires conected to ground like it should have been. It's working fine now. Thanks for all your help and patience .Thanks again Charlie
