Can you guys share some expertise on the pros and cons of using the same amount of ground cable length as the positive power cable (about 15ft) versus just using about 20 inches of ground from the rear relocated battery? I am thinking about purchasing the Summit Racing kit that only includes 20 in of ground cable. Also, some of the past posts in regards to battery relocation have pics that aren't viewable and I was wondering if anyone can show me how to retreive them. Thanks in advance.
