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

First off if you had "someone else" install it, why would "you" have to tap into anything. Your installer is an idiot to say the least. Just by taking two diodes and a relay their problem would be solved. This kinda stuff really makes me upset..... posted_image

Take your car back to the dealer and have them fix it. If thry are complete idiots not to check the car before they finish it and return to the customer, then they should pay for their mistake. Take it back and they should fix that immediately. Those kind of people should not be in business because they do not know what the hell they are doing.

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.
