Fan install question

Hey guys. I have a bit of a problem, and wonder if someone could help me out. I'm putting a Ford Contour dual fan system into my 75 F250. I designed a good system to run each fan on its own relay, so in the event of one failure, I could still make it home.

For the relays I used those off a Ford Taurus, fan relays. As I was getting ready to solder them in, I notice the hot wire (one hot, one ground, on each fan) going into each fan is thicker than the hot wire coming out of each relay. Does that mean a higher amp relay is needed for each fan. I don't want to run thinner wire into thicker, do I?

I am surprised because the Taurus fan is an amp monster. These relays should easily run a smaller fan.

Any help is greatly appreciated.

I don't know the specs of your fans or your relays. I would see if you could find the amp draw of the fans you have chosen, and if you cannot find the info on the taurus relays, just buy some relays that are the proper rating to match the fans. You will need circuit protection and as you said, the proper wiring size for this setup. If you do not know the amp draw of the fans, you will be guessing on all of this.
