I am currently following the relay diagram.
With pin 30s to actuator
(2) pin 87A to ground
86,85,87,87 to 12v
85 and 86 to alarm brain
I have the 4 wires that need 12v soldered together and onto a 12gauge wire. And the two 87A grounds soldered together onto a 12 gauge wire.
But everytime I provide power and ground to those two connections my fuse blows out. I have burned out quite a few 15a and one 30a fuse(checking to see if the amps were the problem)
What is causing this short? Can I not merge the wires together like that?

Hmm after drawing out a quick diagram in mspaint. My ground wires are like this. [ground]------------<======== is this my problem here? where the two grounds merge into one?
If so. Can I ground them in parallel to the same grounding point instead? Or do I need to split them up all together.

okay. I removed the ground loop. Wired them to separate grounds. Put in a brand new fuse. KABOOM. there goes another fuse. Thats fine because I collected way too many fuses from the junkyard.
But back to the question... why is it still shorting?

are u sure the motor rests at ground?

85 - lock or unlock

86 - constant 12v
87 - constant 12v
87a - ground
30 - to lock or unlock wire

im aware that actuators are 2 wires, however there are 2 types of systems.

1) the motor rests at ground, and polarity changes on either wire to lock or unlock. (no switches or buttons)

2) 5 wire alternating, polairty is switched to lock or unlock, but the system rests at ground and has switches.

If you can provide a model number of the actuators we can look them up.

In the first post the relays were wired completely the wrong way round, look at Tedmund's correct posting.
By the way Tedmund, I did that mirror fold, 4 mini relays!
P.S. You're better off using the proprietary relays that come with these kits, then just use neg. pulsed outputs from your alarm.

I think the actuators are reverse polarity? I tested with a 9v battery. with the battery connected one way the actuator locks, and with the 9v flipped the actuator unlocks.
I am using the compustar cm6200 brain and it sends a (-) for lock and unlock.
Its the "gunstyle" actuator in this link http://www.miata.net/garage/pwrlock.htm
I followed that relay diagram at the bottom.

The diagram at the bottom of the page you mentioned is exactly what you need.
