ANOTHER MARK VIII FAN QUESTION.

[mustangnick]

ALL READY TO WIRE MY FAN UP BUT I CANT FIGURE OUT WHICH CONNECTOR IS POSITIVE AND WHICH IS NEGATIVE. MINE IS OUT OF A 97 MARK SO I WANT TO HAVE IT RUNNING ON HIGH AT ALL TIMES.
THANKS.

use a battery from your cordless drill to figure it out, it wont hurt anything!

 

[jrichker]

It's real simple - wire it up correctly and the fan sucks air through the radiator. Wire it wrong and you will feel it blow air backwards out the front of the radiator. Neither way will hurt the fan or make smoke.

THANK FOR THE HELP. I THINK I FIGURED IT OUT

 

[srothfuss]

On my fan (1996 version) the Blue wire is positive and the black is negative (for proper rotation)

are you wiring this up to run all the time or are u using a thermostat or a DCC? I am looking at a mark viii fan myself and i need to know how everyone is wiring it up...thanks

You would want a 75 amp relay or a Dc Controller. I would far and away choose the latter, esp for that big daddy fan (which can otherwise really suck some start-up juice).

I'M USING THE DC CONTROLLER ON MINE. BUT I HAD TO GET A PIG TAIL FROM FORD FOR THE PLUG AND ALL THE WIRES ARE THE SAME COLOR.
