Hey all, apologies for a noob question.

Long story short, I had to give a friend a jump at 2AM last night. I realized afterward that I, half-asleep, attached the negative cable to a different spot on the negative terminal of my (donor) truck than I always have in the past. I circled it in blue in the pic. Green is where I usually hook it up. How bad did I mess up? The cables were otherwise attached properly/in the correct order and the jump went fine. My truck is also running fine today.
