I have 2 cars, one of them is a 1991 Plymouth Voyager. It has power locks and an aftermarket Clifford Cyber 100 installed. It drains the battery, makes the elec. system go crazy and the auto-locks don't work correctly. The door handles are also screwed up and one wants to come off. This system is manufactured by DEI, not the former indipendent Clifford company. Doesnt appear to have valet switch. Do any of you on this forum know anything about DEI systems? Anyone installed any? I am trying to remove it and install the OEM Chrysler system i will get out of a lebaron. The sistem looks like this, seems simple but must have tapped into lots of things because of how everything is screw up and the door handles are coming off. I think it might have hacked into the ignition switch too.
