lvc help

[maxxdude1234]

Hi guys. Does anyone know if this would be any good in my truck: http://cgi.ebay.com/RC-Li-SAVER-Low-...2em118Q2el1247 .

Just wondering if anyone knows whether this will allow me to still use reverse, or if itll only work in forward...

cheers

ps. if people think it will not work, then are there any others out there that might (either 5s or 6s - so the novak lvc won't work) or does anyone have a Li-Saver that they do not want. thanks
