Group, I guess I will put in my 2 cents worth on all the talk about the The Fan Fix Dual 2 x 2 that Special T Auto makes. The Fan Fix has several features that has made The Fan Fix Dual 2 x 2 a desirable Item. I won't go into all of them now but I will say we have never used the wiring harness in the car to draw power from. Note I said wiring harness. Not even the circuit breaker. So, where does the power come from to run the fans. Straight off the battery. That's why when you have purchased one of my units you have had to connect a wire direct to the battery. This way it relives the load from other parts of the harness of the car. I don't had a second edition to adapt to this type of system but because I have never used it on any of my products to begin with. It's now been about 3 years and have had no problems. The circuit is rocket science and can be built if your good with a soldering iron and can get the parts. Also , the price of the Special T Units Fan Fixes have always been very affordable to purchase and are backed 100%. So, If the Fan Zill doesn't use the circuit breaker to get the power from, where does it come from. I didn't see the question answered. P.S. If the web site doesn't give you all the answers your looking for then call up till 10:pm for help.

FanZilla has had an added feature which eliminates the need for the Cooling Fan Circuit Breaker. The breaker does not need to be removed, replaced or bypassed with a jumper. It's no longer in circuit nor is it needed for anything. >>
