As most people are aware, the E46 provides a delayed shutdown for many parts of the electrical system after the engine is shut off if the key is not in the accessory position. This is done to prevent battery drain.
I want to use this feature to control a relay to disable some aftermarket electronics after the delay period expires.
Does anyone know of a location where I can pick up +12 volts that turns off after the delay? It needs to provide this voltage regardless of whether a particular device is turned on. For example, using the trunk lights probably wouldn't work since these are powered down anyway when the trunk is closed. Since I am planning to use a relay, this would not need to be a high current source.
I know that there are aftermarket devices that provide this functionality, but if I if I can utilize the built-in function in the car I'd like to do so.
Many thanks for any info / advice.
