90 240sx Accessory problem

I had a alarm and remote start installed, and the people said that my alarm only came with one Accessory output from the alarm. The problem is i don't know what they hooked it up to, because if i remote start my car, the radio and heater motor don't work. is there another accessory wire that I have to tap into. because the wire diagram on this site only says the Blue on and that one is taped into. And What is the BLACK/ Green wire from the Ignition Switch Harness is that the other accessory wire,

Sorry for the long post, but please help

So i found out why the radio and heater don't work on the remote start. the Heater/ACC wire coming off the remote start doesn't give no volts when the car is remote started. Now is that a problem with the brain. I wrote the company that i bought it from, but still no response. is there any way i could just wire up a relay to power the ACC wire without haveing to send the alarm back.

You can wire up a relay using the ingition output on the alarm because as far as I am understanding the ACC cirucit from the brain is fried.  Here is what to do.  Buy a releay and hook it up the following way.

85 - ingnition output from alarm

86 - ground

30 - high current 12v source fused

87 - ACC wire leading off of the ignition

87a - not used

Hope this helps!

Thanks alot that does help. We tested the ACC wire a little more and found out that it comes on 2 min after the car is remote started. I still think theres is a problem with the brain. Just wanted to say thanks for all  your help, you guys rock.
