I don't have that much experience with the electrical system but I do know that you don't want to over load the system, also don't make it to complicated because then head achs will set in. Your probable doing this already: analysis the system (pros and cons), as well as a schematic of the system, and what other systems are involved. Thats all I would do, but on finding one online go with the one with the most (more than 25) positive reviews.
