door lock relay problem

I have it hooked up exactly like the above diagram, except i don't have the 87a's hooked up to a ground because every time i hook those up to a ground it blows the fuse. without it hooked up to the ground it works fine the currents alternate for lock and unlock, untill i hook up the wires to the actuators. After i hook up the wires to the actuator it shows a +12 reading on both 30's. any ideas? please help, thanks

this diagram only applies if the "trigger" wires from the alarm provide a pulsed ground (-) to lock/unlock. If they provide a pulsed positive (+) instead, you will have to ground the opposite 85/86 terminal to allow the relay to work. Actually, my alarm allowed me to use either pulsed (-) or (+), I just chose to use the (-).

get a DEI 451M door lock relay module on ebay

put the WHITE/ black and BROWN / black wires to ground

put the purple and PURPLE / black wire(s) to 12v

the remaining blue/black and GREEN/ black wires will be your lock and unlock output wires which can be ran to the actuators
