The Jaguars are money pits thing goes hand in hand with "british electrics" which is a holdover from English people having trouble in a rainy country with positive earth cars that had fabric insulation. It kept the reputation after that changed, after the electrics changed to Bosch, and so on. Its all a game of people parroting stuff.
macmon, try plugging in the A/C plug into the radio and see what happens. The computer system is built around the data lines jumping from one module to the next, with each module only pulling off the information that it needs as it goes by. If you don't have the correct jumpers installed in that data line, then you break the stream of data and not all the modules get what they need.
