Clifford RS2: no siren output

I've got the system hooked up and trying to program the system but i have no sound coming from the siren. I've tested the Brown wire coming off of the clifford control box and it is showing that it is ground which doesn't seem right does it? I've given power to the siren and it works that way but once hooked through the control box there is no sound.

Also have a question about using the disarm wire(lt. GREEN/ BLK) hooked through the BCM on the (ORANGE / blk) wire. Do i need to cut the ORANGE / blk wire off and connect it to the disarm or can i just splice into that wire. Any information will be helpful.

MAKE SURE THE UNIT IS NOT SET FOR HORN HONK AND NO IT SHOULD NOT SHOW GROUND IT SHOULD BE A POSITIVE OUTPUT.
THE DISARM WIRE CAN BE SPLICED IN WITHOUT CUTTING"DONT CUT IT "

Thanks for the info..

I got everything else to work on it but now trying to bypass the passkey 3 alarm on there to get the remote start to stay on. Right now it starts and runs for a few seconds and cuts off. But if i stick the key in the ignition and then use the remote to start it it will start and keep running. Need to figure out the best way to bypass the passkey system using the relay and resistor on it.

Getting a bypass mod is the easiest way. for PK3 use DEI part# 555U for this.
