I've been following this post and I've had the same problem with the trunk not opening. For some reason, I've been lucky and after several attempts, it's suddenly opened. But I am very interested in finding out if you can jump or charge a 380 from under the hood. I did a search, but came up with nothing. If someone out there knows a jumping point under the hood, please post it. I'd also like to use the hot location for using a timing light when tuning the engine.
