HI all, did lots of searching but the info I found was kind of vague. Installing a Codealarm in this Jeep. It has no factory alarm but did have a dealer installed Karr4040a. I can't figure out how to get the pass and rear hatch to lock/unlock. They ran wires into the drivers door and it will work with the alarms neg output but the rest dont. I found 2 wires (same as the wire diag shows, pink and a orange) that they tied into that pulse 12v when you hit the lock/unlock switch but no luck getting it to work using relays to send pos to them. I have no idea what the old Karr was doing to them, cant find a diagram on that alarm. Are they maybe reverse polarity? Ran out of time will look at the car in a couple days. Any advice? Thanks!
