I had this exact system. If anyone is interested in removing it: It has a bunch of "fake wires" acting as taps into the wiring harness, and it detects if you remove a tap and then trips trip a relay where it cuts the ignition wire that is rerouted through the unit. So I removed the device, and put the ignition wire back together and the car was back to normal. I think if OP's car still has warning lights go off, he likely nicked some of the other wires inadvertently, or broke them while pulling the taps out.
