99 civic proximity sensor

i have a 99 civic decided to replace a decade old alarm . removed the old clifford concept 400 alarm and installed a clifford 50.5 i want to install the proximity sensor from the 400 . Im unsure of how to wire it up . it has 3 wires a red , black and a white and blue wire . It came wired into the concept 400 and on the 50.5 it says it has 4 auxilary inputs but i dont see them . any questions that would help feel free to ask . oh and by the way not using the remote start because its manual so i have depined a lot of the wires .

You can't do it! They aren't compatible I'm afraid.
