Finally it arrived from Hong Kong , pretty fast about 7-10 days, just really SAD you can't buy something simple like this in the Silicon Valley 200,000 sq ft FRY's or at Radio Shack. The guy working there did not even know what the hell it was, just amazing. No wonder America is going broke.
It comes with a 10 amp fuse and you install both the + & - from the power & load out to the fan. 4 connections. Seams simple enough ... Will report back when it's completed.
