Has anyone done this fan mod and if so, i dont understand the diagram. What is the box that has all the wires running to it? is that the toggle switch or is that something else. I am trying to do this to my ta but can not untill i know what that is. thanks also if that is the switch which i think it is, there is not a positive (power wire) going to the switch so how is it supposed to supply power?

Yes, the "box" is a DPDT (dual pole, dual throw) switch. There is no power running to it, because it only supplies a ground to operate the relay(s). No power is needed.

You also might want to use this diagram if your car is a 97. You will get trouble codes if you don't use the 47 ohm resistors shown on the left. The diodes are not needed unless the LEDs don't work right.

Sounds like you might not be too familiar with wiring and schematics. Perhaps there is someone in your area that could help you with this mod.

 

Thanks shoebox, that answers all my questions, and no i am not very litterate when it comes to wiring diagrams, but now that I know what the box is i know what to do. Also thanks for your site too, it has a lot of helpful stuff for me. Keep up the great work on the site.

 

Technically, it is not hard to do, but diagrams can spook and confuse people. The last thing you want to do is fry some wires or expensive components. Good luck.
