You can have several relays on one maxi fuse because the relay carries the load. (www.spalusa.com) detailed wiring diagrams on web site, check it out.

The fans came mounted on the radiator which I believe it is Ron Davis radiator. I bought the car with this setup and frankly speaking I am not sure how the idiot who wired the car did the wiring of the fans because the relays and fan wires are not the ones supplied by Spal Fans.

Thanks for the input on the fan wiring though, and I am going to go the wiring schematic of Spal Fans once again
