I have a Ai606 I've already fitted two stage proximity, and am about to fit a digital tilt sensor (single stage, no pre warn) and two stage shock with pre warn and plan to fit glass break as well, so will have two single zone and two dual zone sensors. I know I need to use diodes to each sensor when I add more than one to each sensor input Are the sensors +ve or -ve trigger, which wires need the blocking diodes and which way round? I have fitted the Prox sensor which is working well but... It it better to fit the tilt sensor and shock sensor horizontally on the floor pan or vertically on the bulk head??
