Porsche 944 Turbo Alarm System Troubleshooting (1986 - 1989)

If you are chasing down a no start situation with your 944, one of the first places you may want to apply some attention to is the factory alarm system. These systems did not age well in the vehicles. While it is very difficult to test the alarm control box, it is easy to bypass it and eliminate the alarm as an electrical no start issue.

The alarm control unit or box on the early 944s is located behind the radio. On the newer cars it is behind the kick panel in the passenger footwell. You are going to need some 14-gauge wire and four male spade connectors to make two jumpers. While I do not recommend driving the vehicle with the alarm jumped, if the alarm is the problem, this can get you home in an emergency. If you want to remove the alarm, you should get a proper bracket and permanently remove and jump the alarm. All Porsche 944 and 951s came wired for a factory alarm.

The space you will be working in up behind the glove box is very tight. If you feel you want more room, you can remove the glove box. Please see our article on glove box removal for additional information.
