douellette Posted February 8, 2010 Report Share Posted February 8, 2010 is there a way to wire up a toggle switch to the factory fans and still have them function like normal and not have the check engine like come on at the same time? currently i have a switch wired up to one of the relays for the fans ( i cant remember which one) but it makes the check engine like come on (even if i dont turn the switch on) Quote Link to comment Share on other sites More sharing options...

Straight from the text above the image: "You will leave the stock relays in the relay center. There is actually no need to even open up the cover. This modification will require 3 additional relays shown below that can be purchased at almost any automotive parts store. They are most commonly used to control auxiliary wiring."
