how to wire aux fan to ignition
 

I have a 96 I wanted to have the fan turn on whenever the key is on how can I do that either a way to mess w the relay or splice into a wire any help please

Run a wire through the fire wall from the hot on the fan to the red wire on ur radio??

You should have an accessory slot in your fuse box run the power wire from your fan to that slot and it should work.
