Would need to be a heavy gauge cable too.This might not be, (probably isn't), practical, but you may be able to disconnect the fan from the FCM completely, and hard wire the fan to the fused side of the fan fuse, to give permanent running of the fan at high speed, and rule the fan speed in or out as the cause.
Would probably need to get the engine hot first, then run the fan.
Sounds a bit daft now I've written it ...
