Did the manual fan switch mod this evening on my 97 Z.. Works great fans come on exactly as they should.. used http://www.xious.com/camaro/install-fanswitch.html as instructions. Only problem when the car is running, if I kick the fans on after about 5 seconds the SES light comes on.. I soldered all my connections so I know they are good.. can anyone help?? TIA

Add the resistors in this diagram and it should stop the SES from coming on.

 

1 resister on the green and 2 on the blue piggy backed? I really appriciate the quick responce, thanks a lot!!

 

Yep, just like the diagram. The two resistors are in parallel. Those that have done it, have told me it worked well. Thanks to KCLarson for the diagram.
