electric fan / alternator question

their is no reason to run all that currant through the fire wall plug unless you insist on haveing an amp gauge.your just asking for trouble.run a heavy wire from the alternator to the 12v buss in the motor compartment and wire your relays to the same sourse. fuse every thing. it will be safe and trouble free if done right.(buss is the conection point of the fat positive lead coming from the trunk)
