I put a full ballast system in my 2001 Supra SSV( before they came standard). It works awesome and is hooked up to two switches. Works great and gives me 1000lbs in 10 minutes.
E-mail me and i will tell you how to do it. Let me know what supply's you have(fat sacs, pumps) and then we can estimate how much it will be to complete. Also let me know what boat you are putting it in and where yo uwant to put it.
