[Fusion]

Hi Guys . I've just bought a twin thermo fan setup off ebay . Surprise surprise it has no wiring diagram and can't get any response for the seller .So I thought i would see if any of you guys could help me out .

Now i have 4 wires . Red (main power with fuse ) , Black (earth ) , Blue (power supply out of relay ? ) and a White wire .

I know how and where to connect the red , blue and black wires but what and where do i connect the white wire ????? some advice please guys . Thanks

so does the fan setup have its own in-built relay? if so i would guess the white wire would be earth for the relay.

the rubbish diagram should shed some light. the relay needs to have constant + from the battery, ignition +, an earth, then the feed + to the fans.

i hope that helps. also note that if they are fair sized fans you will need two relays to cope with the power drain if you are hooking them up to ignition + and not a thermatic switch.
