Ok well, I tryed following this webpage
07-08: How to Add Shock and Tilt Sensors to Factory Alarm - my6thgen.org - Maxima Forum since the link is dead in this page
Aftermarket Alarm Features with Factory "Alarm"??. i plugged everything according to the diagram attached using the same sensors however using the wires for power, acc, ground and trigger on the the370 webpage above obviously. Using the diagram attached to this post is how I connected to the Z.
The only difference is that i wired two shock sensors (one for front, one for rear) together with the tilt sensor into the timer and relay as shown in the diagram.
This diagram did not work. No click at the relay, shock sensors light up, no sound from horn or lights. Can someone knowledgable look at this diagram attached and see if it is actually correct?
Any help is much appreciated
