I have read in other threads that you need a thicker gauge cable connecting the starter battery to the house battery, preferably with an ACR in the middle. I think this means you can't use the +12V pin in a 7-pin connector. Is there a standardized (large 2 prong?) plug that sits next to the 7 - pin connector on the TV? May I see pictures of what this looks like?
Thank you for your help.
