clifford omnisensor

so the g4 omnisensor is no more dei has the g5. i would like to verify my idea. can i take a g5 omnisensor and hook it up to the g4 alarm simple by cutting the RED / black wire feeding it the 5v and rewire to feed 12 v and all should be good   am i correct?

so you have to love dei tech support....  they told me the g5 omnisensor will not work with the g4 clifford and when i presented the idea for cutting the RED / black wire on the g4 alarm (which feeds the sensor 5v) and rewiring it to 12v to turn on the g5 omnisensor.... at first you would have thought i asked him to take a hit of a crack pipe and then said hold on and came back and said "it sounds like it would work" .... i think it will work because we are just turning the sensor on and not affection the digital info.   i would just like some 3rd party verification before i invest the time to get on my back and rip the dash out.
