alarm with relays built in stumped

I'm having a dumb moment. Currently, I have shaved handles and locks. I have the driver side hooked up as the unlock and the passenger side on an auxiliary channel. The relays are currently set up for a negative pulse. My new alarm that I'm going to put in has a built in relay. The new alarm has: Unlock - 87A Lock 30 Unlock 30 Lock 87A Lock/Unlock 87 (power in) So I'm guessing if I just wire the Unlock common (30) to the existing coil (85) from my door solenoid relays, it would work? Or do I have to do anything else?

The wire labeled Lock/Unlock 87 Power in needs to be supplied with power or ground, whichever you need to trigger the relays you have. 

So I'll ground the 87 and then the unlock 30 should give me a negative pulse, correct?

Show me the information on this Alarm.

http://www.scytek.net/manuals/astra/a7E7.pdf - this is identical to what I have except I have a different 2 way remote.

Don't use 87a lock or unlock, Don't use 30 or 87 lock. Unlock 87 to ground, Unlock 30 to relay 85, aux to other relay 85. Rather like the Ford Mondeo (think Ford 500) I had the other day, unlock neg. trigger worked, lock didn't - faulty GEM module so I had to wire unlock as a neg pulse output and the lock as a 5 wire to the yellow/black motor wire.

Thank you kindly everyone. Howie - my first experience with the GEM was with a Ford Mustang - didn't know about it and installed a proper remote start for a standard transmission. Guy brought it back, said it didn't work. I set it, started right up with the remote start. Next day, same thing. Started right up for me. Then I did some reading and learned about the Gum Everything (up) Module.
