Sorry to bring this topic up. Since I know its been beaten to death in the past. But I have searched and looked everywhere. And I just cant find a 5 point relay. Where are you guys getting these things? I find 4 point relays everywhere could I use a 4 point? Or should I hold out and go for a 5?

 

you can use a spst(4 post), but you will probably need 2, one to break the shock sensor and one to break ignition, depending on what kind of alarm you have. You can get them at any reputable car audio shop, if you don't know much about relays and how they work I would also suggest letting them do this for you.

 

or you could just hook the ignition input of the alarm to the radio wire in the car (whit/black) found at the ignition harness.
