Mazda CX 7 R/S Locks And Disarm

Mazda Cx7  - Compustar Cm6200 and blade TB

When the vehicle remote remote starts the alarm goes off. I think this is due to the factory alarm not being disarmed.

Looking over the forums i found this..

LOCK  GREEN/ red  In driver's kickpanel    - 

   One wire doorlock system. Ground through a 1K-ohm resistor to lock and straight ground to unlock.   UNLOCK  GREEN/ red  In driver's kickpanel    -     One wire doorlock system. Ground through a 1K-ohm resistor to lock and straight ground to unlock.

 FACTORY ARM  BLACK/ white  In driver's kickpanel    - 

   One wire security control. Ground through a 1K-ohm resistor to arm and straight ground to disarm.   FACTORY DISARM  BLACK/ white  In driver's kickpanel    -     One wire security control. Ground through a 1K-ohm resistor to arm and straight ground to disarm.  

Can i run the leads from the R/S (Lock - with resister ,Unlock, Arm - with resister, and Disarm) to the factory wires directly.

Or does each need to be run thru a relay?

And will this provide me with a proper ground? Or do i need to use these as triggers and provide a body ground?

You must use relays to provide a good ground. To hook up the locks and alarm, use the remote starter's disarm output (through relay) to the disarm wire (BLACK/ white). Use the unlock output from the starter to the vehicle's unlock wire (through relay). Use the remote starter's lock output (through relay)to the vehicle's rearm (also locks doors) wire and insert a 1K ohm resistor inline. You won't need the vehicle's lock wire.sparky

Use the Lock and Unlock output from the R/S (White 6Pin Connector. Blue - Unlock, Blue/Black - Lock). Wire it straight to the BLACK/ White on the BCM (Lock goes through a 1K ohm resistor), no need for a relay. BLACK/ White controls lock/unlock and arm/disarm. Leave the R/S on the default 0.8 pulse to unlock all doors. Program the R/S to unlock before starting, lock after starting. It's option 1-01, setting 2.

If I'm going this far, I might as well connect the lock wire inline with the resistor and add the lock function to the new fob. How to I test for correct lock wire? Or just hook it up and try?

I don't understand what your trying to do here. The BLACK/ white wire on the BCM does lock and unlock along with arm and disarm. One connection for everything. Connect your unlock output from the starter straight to the BCM. Put a 1K ohm resistor on your lock output and tie it to your unlock output wire, or run it to the BCM, same as the unlock.

One that connection has been completed, program option 1-01 to setting 2 to solve the alarm when r/s.

Meter for the correct write while turning the key in the door cylinder.

And you WILL need relays, the lock/unlock out puts don't produce enough current to get past the resistors and this applies to ALL alarm-R/S units with 2 wire NEG (-) lock outputs. Been there done that.

Forgive my ignorance.......

When i meter, Red Lead from DMM to 12v and black lead to WHITE/ black?

What should my DMM read when i turn the key in the door?

12v+
