clifford 50.5x adding 508d

Hi, I have a Clifford Matrix 50.5x remote start that was installed by a local shop. I now want to add a proximity sensor (508D) to my convertible after a break-in. I want to figure out if I have any inputs free before taking apart my dash or ordering the part from Directed! I have the shock sensor that came with the 50.5x, a tilt sensor, a hood pin, a trunk ball sensor that detects when it is tilted open. I think it tied into my stock door pins, and there were door lock actuators added on. I have the original 50.5x siren and the added backup battery siren. FYI, my vehicle is a 2000 Mazda Miata LS Thanks.

Wire up the 508D like that so that when the alarm goes off, Sensor 1 is Shock Sensor, while Sensor 2 is your Proximity Sensor. Note: You Always Dont Get What You Pay For.

So basically the brain's blue goes to shock sensor's blue and green wires. The brain's green goes to proximity sensor's blue and green wires. I thought my tilt sensor was zone two though... do I have enough inputs? Thanks!

its okay to have 2 sensor for one input, since all your other inputs are already being used up. But when the alarm goes off and u see Sensor 2, you wont know if its the tilt of the proximity sensor that triggered it. Thats the only down side, but i really doubt u care, as long as your car is protected, right?Note: You Always Dont Get What You Pay For.

If it's a convertible why in heavans name didn't the shopsuggest one in the first place?
