I try connecting the shock sensor to the 3 port connection of the Evo-One, but when testing the port it has no positive output, and from what I can tell no ground. How could I hook up my dual stage shock sensor to this great all in one unit. I have my smart start hooked up and running as well as my parking lights working (-), thanks to Jesus' quick detailed replies. Is there a setting I missed or perhaps a pair of wires I could connect the signal wires to and ground the negative and get power from another wire when armed, similiar to the evo-all.
