Yes, that is correct. In fact, I wired 86 to my arming switch, positive side and 85 to ground output from window switch. Your going to like COS5.

Ok like such-

85-ground output window switch
86-positive side of arming switch
30-chassi ground
87-pin 56

Why did you use ground from your window switch?

Thanks very much
