I'm installing an electric power steering pump (the TRW pump used by lots of others) in my 2007 Cayman-S.. To prevent the pump from killing the battery by running when the engine isn't running, its suggested to connect the pump's trigger wire to the alternator output signal. Unfortunately that's in the back of the car and the pump is in the front. Does anyone know a convenient signal in the front trunk that goes to 12V only once the engine is running? -js
I believe the start lock relay is part of the immobilizer function — prevents cranking if conditions aren’t met.
Finding the alternator signal at the ECU is easy. Just trying to avoid running a wire if there’s something already there.
Thanks-
