Engine bay electrical connections.

[X5smw]

Hi all, hope you are all well. 
I am looking for a ACC switched positive wire in the engine bay if anyone knows where I can tap one from. E53 3.0i 

I have found a permanent positive but I need a switched one too instead of tuning a wire through to the back of the dashboard… cos I’m lazy and time is not on my side. 
any suggestions please.

If this is for your Angel Eyes on the S53 I took a power feed from the where the ECU lives take off the lid and where the loom connects 3rd wire from the left is Red/white trace, earth I used the Headlamp earth so only running a single wire for power. This power feed is ACC switched but remains live for 20 secs after key out. You can test by sticking a pin into the wire and using a tester
