I would like to have it so that when I arm the alarm it "disconnects" the fuel pump so the car won't start/run, then when I disarm the car will be able to start/run......

How can I do this? TIA guys/gals

use the orange wire (starter kill) to open a relay when armed .

an alternative if you have a detatchable face -

when the face is out the pump is off - use the remote wire to power the relay for the fuel pump...

check out passive starter kill with remote turn on lead....this works great . at 87a connect a bulb or led with resistor to ground to indicate that the face is off when you try to start .

be careful with fuel pump cutoffs. just remember if that circuit ever fails you will stall imediately and it will be at the worst possible time. remember murphys law what can go wrong will . like on the freeway doing 70. not a good time to have that fail... just my $.02
