Put a Champion 526 radiator in a 71 swinger?

Hi, the 12 volt constant does supply both the relays and the controller but the instructions for the controller tell you not to use the same 12 volt source as the fans. I actually ran a separate 10 ga. wire from the battery to run my fans and pulled the 12 v constant from my fuse box. I hope this helps. If you have any other questions don't hesitate to ask. Dave
