Welcome. This is a mod that we do often. What you need to do is move the battery from the passengers side to the drivers side, then get a new battery, a 78 series dual terminal. Attach the cables from the original battery to the top post of the new battery, then make new cables that run from the top of the old battery now on the drivers side and run them to the side post of the new battery. This will keep all the charging properly working. Do not run the negative to the chassis, only to the new battery.
Is it possible to get elektrikal flail?
