murfanater

Okay awesome so I hooked up the open system radiator with overflow tank, and an aftermarket 10inch fan and it is all looking awesome. Two more things I need to finish though. First where should i hook up the fan and how? Its electrical so where should i hook it up to? Also I still got the old tank in there from the closed system. The people at auto zone said it would actually be smart to leave it in so it could hold more fluid. should I take it out and bypass it or leave it in? thanks!
