I'm stupid but where is the prong? it's been a while since i watched this thing get installed..

 

When you look down on the fan from in front of the motor it will be sticking up to your left (passenger side).

are you sure about that? im almost positive that all flex a lite kits come with all wiring, mounting brackets, etc.

directly from flex a lite web site:
"Includes new Variable Speed Control
(60% to 100% depending on cooling required)"

how could the kit come with the variable speed control and not include the wiring??

 

Yea, what he said.

oh I could be wrong. I just remembered that they had a sep. efan wiring kit right next to that product so i thought it went together. i guess i was wrong though...

 

I might be wrong about this, but I think the JDM kit is controlled by circuit breakers for hi/low controls. There is a 30amp circuit breaker included with the kits and an optional 40amp for track use. This has lead me to believe they are just letting more current through the wire harness to operate the fan at higher speeds.

I had a problem with my fan a few months ago and my installer put a 50 amp fuse inplace of my 30amp circuit breaker to get my fan to operate faster. My truck was overheating late last summer and this solved the problem. I was not aware of what he did, but now now that's a dumb a$$ thing to do. The wires going into the fuse and out, burned completely threw. In my opinion the harness is not correclty designed.

 

Big help there Tim.

Other than the obvious numbers on paper, does 2000 more CFM cool the engine more and/or faster?

And does it really matter?

 

More faster I think.

 

Here's the deal on the JDM kit:

High is always controlled by a simple switch run through a 40A circuit breaker.

Low is controlled by two relays: A/C on or temp high enough then run though a 30A circuit breaker.

My theory is this: due to where JDM mounts the circuit breakers, they can overheat and trip during really hot days. This will turn the fan off for a couple of minutes while the circuit breaker cools down, thus causing the truck to overheat.

I replaced the 30/40 with 40/50 and everything is fine.

There are definetly two speeds to the fan and the speed is controlled via which wire gets power, not by any current limiting device.

Watch your wires, running that much current with 16 gauge wire can't be good.

My fan ran fine with the 50amp fuse but the two wires going into the fuse and the one coming out burned completey off and the fuse never blew. So the wires in the harness can't really handle that much current. I went back to the 30amp circuit break for now!

 

This is our JLP Fan Kit..It comes wired up in a new factory shroud and includes a cobra water pump..$ 450.00 Don't let that smaller dia. fan blade fool you. this unit will move more than enough air to keep our trucks cool on the hottest day sitting in traffic with the A/C on! Plus it does work automatically with the A/c and temp. sending unit.........JL

I agree.....16awg is WAY to wimpy of wire for the current these main fans pull. I used all 12awg wire and never had any problems

I have been told by my Tech to replace all the wire in the kit with thicker gauge, think I will be doing that soon. Glad to see I'm not the only one that thinks the wiring is insufficient!
