ok so I have the fz1 fuze box hooked up from battery both connections with their kit I purchased, I am trying to find a good positive source to tap +12 into, I have tapped into the gas guage as I read somewhere else but the problem is how do I check and see if everything is working properly, I dont have anything to hook up right now I just was doing this for future adventures, any advice would be appreciated, or if anybody has a better tap in source please chime in, thanks
