When installing battery minder do you need to hook it up to the battery or you can do it in the engine bay? There must be an easy way to connect it. I just bought my battery minder and not sure if I should install it directly to the battery. Just got the car over a couple of months and the battery is dead. I did turned it on every couple of weeks but yesterday it won't start. I can't wait next spring. Need to have fun with my snake. Any suggestion???
