This is a quote from one of the tech articles on this site. I am removeing the ecm from my '87 IROC OE'd with dual electric fans. Can this part function with out the ecm helping it? I have all of the original wireing for the car that I can use if I need to but, for the sake of clutter, I want to remove as much of the old ecm harness as possible.
Thanks

First, I wrote the article. The products I outline in the article are designed to add electric fans to a car that's not originally equipped with such. This requires some modifications to the factory wiring.

In your case, you can use the Derale and/or Hayden to control one or both fans. Just follow the directions supplied with the kit.
