Need help wiring up two electric fans

[Destructo]

Alright, i'm basically re-wiring the fan on my truck since I just added another 10" aux. fan.

I'm going to be getting two 30 amp automotive relays, one for each fan. Have on/off switch for each fan and a thermostat for the main 16" fan. Also have inline fuse blocks to go in-line, will I need the fuses since I will have relays in the line? I have 10 guage wire to do this with also.

I want to run one 10 guage wire from the battery into the cab then split it to the 2 switches and pipe those two seperate wires to the relays and then to the fans. The wires will be pretty long, especially from the battery to the switches since the wires will go in on the driver side of cab and the battery is on the passenger side.
