power lock problems!

ok. I ordered an alarm and lock set from autoloc. the thing included a wiring diagram but its a litte vague. Ive done all I can, and the alarm is working fine. the receiver is getting the signal, its making all it slittle noises, it goes off when I bump it. the alarm is jussst fine. I AM though having a lot of problems with the power locks. I just cant get them to operate at all. I wired up 2 relays like I thought I was supposed to, but they dont work at all.
does anyone have a guide, or a better wiring diagram (exactly which wire to where on what relay type thing) and ANY kind of insight for me?

for reference its a stellar st7000 alarm and cl2000 locks. and ive got 3 30 amp relays

are the relays standard 5 pin automotive relays with pins labled 86, 85, 87, 30, 87a.

ok well maybe Ill ask something diferent then.

how do the door locks work? there are 2 cables coming out right, the greena dn the blue.

here is my impression after a day of tinkering:

I have two relays. These relays act as switches, and the switch is engages whe a signal is sent through the 'coil' of the relay. when the signal is received the n/o part of the switch closes, allowing continuity from the power source (or whatever it is) to the device the relay is attacthed to (in this case the door locks)
I imagine I need two relays because I neeed both a signal for LOCKING and UNLOCKING doors. this is where I get messed up a litttle....

the two wires on the locks are normally both - or grounded when both relays are at rest. when a voltage is applied to either wire, a circuit is formed causing the motors to operate. ie.... in my case, 12v greena and a negative blue will make them lock, and a 12v blue and a negative green will make them open (though I dont know if it is int his order or not... can anyone offer some insight?

so yeah.... do I know at all what im talking about? I believe what ha sreally got me confused is the wiring diagram, seen here:


er hang on. ill ahve to grab it in a sec

Okay two relays, 2 door lock motors, Two wires from each door lock motor right???

If so wire as follows:

Blue wires from both door lock motors to 30 of one relay

Green wires from both door lock motors to 30 of the other relay.

12 volts+ on 86 and 87 of both relays

ground (-) on 87a of both relays.

The keyless entry's small blue and green (or what ever color they use as outputs for negitive door locks) hooked to 85 of each relay respectivly. You can also test to see if you wired correctly, by if it tap ground onto 85 of one relay for a second, the doors should lock, and if you tap ground onto 85 of the other relay for a second the doors should unlock.

And I do not see any wiring diagram... did you try and post it???

ok yeah makes sense, thanks ice. here is a similar wiring diagram. the green arrowes point to the lock and unlock signals, I understand these jussssst fint. makes sense. circled in red are the two wires I have nooo idea about. they are not giving off a voltage when the doors are locked / unlocked so I dont think, at least I couldnt detect one. Im not sure if there is supposed to be a 12V IN TO one and a ground IN TO the other, or if there is 12v coming OUT of one and a ground coming OUT of the other.

The two wires you have circled are for the door triggers (or also called door dome light switches). Mazda uses ground for the door trigger, so you would hook the Brown wire of your keyless/security system to the Mazda door trigger (as I recall blue/red at the CPU or the factory security plug- but double check... I posted the alarm wires up in a thread a year or so ago, and am just remembering off the top of my head).

The white door trigger from your keyless diagram won't be used, as Mazda does not use (+) door triggers.

Now the Green/White from the keyless/security unit should be going to the 85 of one relay with the blue/white going to the 85 of the other relay (this are the relays that I talked about in the last post). According to your diagram the oranges should not be used as they are listed as N/C (normally closed or Normally connected), but if there is a typo, and they should really be N/O (normally open) then they will need to go to ground.

hey ice donno if your still around but I have one more problem.

my wiring diagram says that the door trigger wire is bkue/white at the theft control unit. so im looking udner the glove box,a nd I see TWO blue wires with white stripes. one is big and fat and one is the normal size, smaller, like most of the other wires.

which one should I tap?

OH and last but not least.... ive got the antenna lead coming out. its jsut a black wire. can I hook it to a ground on the frame? will it allow the body of the car to act as an antenna?

No you can not ground the antenna wire. Do not cut it either. It is a length of wire that is tuned to the freq that the remotes work on

The door trigger will be a small gauge wire, with 12 volts on it with the door closed and ground on it with the door open.
