Ok, so I'm trying to wire the relay to the door lock actuator and my alarm. I have a Huatai HT-400C alarm and I'm trying to install it on a 2004 corolla ce. I got the actuator to move once but that was it. Can someone figure out this wiring diagram? Tell me which wire goes where?

Please post the color and description of wires from your alarm that have anything to do with doorlocks.

Well the color of the wires from the alarm is in the first diagram, and the actuator has two wires which are black and blue.

Well, by looking at the diagram on the left, it looks like your alarm has onboard relays, so no external relays will be needed.

orange and ORANGE / black go to ground.

Yellow and yellow/black go to constant 12v.

white will go to one of the wires on the actuator, and WHITE/ black will go to the other.......if the locks are reversed after it's hooked up, then just switch the white and WHITE/ black wire.

if you already hooked it up incorrectly, and tested the alarm, there is a chance that something might be damaged now.....good luck

So you think the actuator is damaged? Can the actuators break that easily?

No, the actuator wouldn't be, but if you had the wires on the alarm hooked up wrong something could of been damaged. i would hook it up like i have listed and give it shot....hopefully everything is still good.

Ok so I wired it like the diagram without the relay but it still didn't work. The actuator didn't move. Thought the actuator was bad so i tried it on the passenger side door. Same thing. Don't know what I'm doing wrong. One thing I noticed when I had tried to wire it with the relay the first time was that I heard the relay click when I tested the door lock but when I put a fuse in that wire, the relay didn't click.
