Many Thanks for you valuable information, Actually i had my radio and lighting off and couldn't find where was the problem, now I think it came from the power switch if I am not mistaken.
Oh yes, for the smart tabs, i order a pair and waiting for it.
I only install a fish finder Garmin 500 C for the moment, also the insulation to the under-seat cooler is an excellent idea since i didn't even thought about it .. lol.
Thank you for the information and if i have any other blind spots I will come back to you.
