Passive or active starter kill or both

i have a normal starter kill on my alarm 

,but is it possable to add a passive one just in case i forget to set it

i have a Black Widow BW-852 keyless entry system with OPTIONAL Starter defeat output

You can try hooking on your starter kill relay to the seatbelt wire. this way if you dont have your seatbelt on you cant start your car. I did this on one of my buddies car. I recommend it because one its safer for you and two wat thieft is gonna put on his seatbelt when he stealing your car. Or you can do it anothor way you can hook up terminal 85 of relay to your clutch wire that gives negative when u depress the clutch and 86 to the brake wire. this way you have to be steping on the brake n clutch to start reguardless of alarm status. If its an automatic hook terminal 86 to your parking brake wire. just a few ideas to help you out. It might seem like alot of trouble for you just imagine for a thieft, after awhile it will be just like anything else n you'll be use to it doing it without any thought.
