I have a question about the efan wiring kit. What fused wire did you tie into for the yellow signal wire? Also, after you installed it, did your fan run after the truck was turned off? Mine runs till the radiator is cooled off, then cycles on again when the fluid warms up past 180 degrees. The run cycles get shorter and shorter till it finally stops running altogether. Thanks in advance,
Justin

 

sorry I was in Ohio for the last few days...

let me see if I can find the picture.

My fan only runs with the key in the "on" postition.

It sounds like you ahve the ignition wire hooked up to a constant on power source. Reason being is that the it turns on wen the engine is off and key removed.

The temp sensor on the radiator will trigger the fans on if the ignition is wired constantly on.

I think this is what you are looking for

Since my fan has 2 setting, High and low, I have the temp and A/C hooked up to Low setting.

I have a toggle switch that I will simply hook up to the high setting, so when I'm at the track I can pop the hood and flip the switch to help cool down.



If that isn't what you are looking for let me know. I have to go "visit" the L this weekend and give it it's weekly startup and warm up (in storage) I can take a few pics ...

 

That will work. Yeah, the destructions said the red wire goes to the battery. I may have to change that.

 

One more thing menace, what is the red wire going to, and what is the white wire? Which is the yellow ignition signal wire on the t-stat box? Thanks again,
Justin

 

its' not my picture (stole it from someone on here) but mine is exactly like that.

Currently the truck is in sotrage so I can't pull the wires and tell you exactly which is what.

However, One of the wires is an ignition switch and the other wire is the a/c relay.

I'm sure you know how to test the lights:

Grab a test light and determine which is the ignition.
Put the test light on it, put key in ignition and turn it to "on" position. If the light comes on it it s the ignition wire.

For the other wire, start the truck, and put the test light in the where the other wire is. Turn on the A/C and the Test light should come on.


If you need anything else, just hollar
