The alarm unit only has one input for a 3 wire connection which is used by an impact sensor... however, I bought a motion detector and would like to install this as well as the impact sensor..

If I wanted to do this... how would I go about doing this? would I Just splice into the 3 wires connected into the alarm unit and connnected the appropriate wires? can I do this with multiple modules??

Get power and ground from a different source. You can use the same trigger wire, but you will need to diode isolate the two wires from each other. Read the section here on the top left about diodes.
