Hi all,

 

I need some wiring help on installing a spal 7.5" fan on my transmission cooler. Here is the link of the instruction of the fan controller.

http://www.haydenauto.com/pdf/instruction-sheets/P-475-3647-fan-controllers.pdf

 

On page 1, second column, #3,

"Yellow wire (ignition signal)- Attach the yellow wire to a positive (+) 12 volt connection that is controlled by the ignition. To allow fan(s) to operate with the ignition off, connect the yellow wire to a constantly live (hot) lead."

 

Do you all know which wire in the engine bay that is a 12 volt controlled by ignition switch? (12 volt only when key is ignition on position, NOT constant 12V when the key is off)

 

Your help is much appreciated in advance. Thanks
