Given you do not remove these fans very often, I would recomend avoiding the plugs and hard wire direct to the relays and then main splice down by the voltage regulator. If the plugs get loose but not unplugged you will over heat and destroy the fan motor. Using the main splice rather than the fuse link junction on the fender will give a better reading on you battery guage. The wire from the battery to main splice is a bit small so it is best not to run the fans very long without the alternator spinning. Bottom line, theses fans compromise the electrical system to some degree without a weekend's worth of harness rework upping the battery charging wire size. It will numb the battery guage some but you will get correct operation of the guage and have less of a chance of cooking the harness going to the front right corner. If you simply wire to the fuse link junction terminal as most do, the battery guage will confuse the fan drawing power as a charging state to the battery. This is exactly opposite of true state. Placing the connection for fans at the main splice puts the power draw at the correct end of the battery guage shunt wire within the harness. Having a 70+ amp alternator is required but will not fix this guage problem unless wired correctly.
