I thought that I was done for a while but now I am working on some timeing on the 350 chevy and came acrossed a part that I heard when trying to start it up,the noise was a clicking niose that was coming from a little box on the front passenger side fender. The box is aprox.2"x2"x1"thick. The box had 2 wires coming off it. When I did the swap I pluged the wires back in and thought nothing about it. What is this and do I need it? Would this box mess up the timeing or vacume on my 350? I would love to know what this box is. Thank you Aaron
