Thanks for the input - and you are correct, I found out a couple of things - and some good info for anyone else installing one of these yourself, the vehicle will NOT run without the RAP module or the newer version as in your case. However the newer alarms like the Matrix RSX 3.5 by Clifford will actually arm & disarm the factory module as it arms and disarms itself - so it works in conjunction with it. The wiring diagrams on the TSP Disk are too vague for alarm installation. So will be looking for resources on the net for wiring info...
