[QUOTE="Water Bear, post: 8822050, member: 673826"] Yep, right on. Your trunk battery is in parallel with your under hood battery I assume - positive to positive, negative to negative. If so, grounding on the battery negative should work. If you see a spark when you connect to the negative that probably means your battery negative and original ground were not at the same voltage.
