Revan Racing Posted January 3, 2010 Report Share Posted January 3, 2010 Just trying to determine where Ford relocated the relay that activates the heat exchanger water pump so that those of you who have purchased the Shelby Heat Exchanger can also by-pass the ECU and trigger the heat exchanger and water pump at key on. Please take a pic and post. Thanks Van Link to comment Share on other sites More sharing options...

Also looking forward to receiving the upgrade you've recommended for my 10 as well, the mod bug had bitten me hard! Thanks, Bish Link to comment Share on other sites More sharing options...
