Hi all.. Hope somebody can help me with this. I have a 1991 300 SL 24. My battery is dead, and i cant open the trunk with the key. I need some power to get it to work. A friend told me there should be an battery connection under the hood also. I cant find anything. Some clue please??

 

I don't remember if the 91 had one BUT you can certainly apply your power to the starter lug as it comes directly from the battery..
