Hi Guys. Ihave a 62 vette, LS3, 4l65E, E38/T42. Does anybody know how I can operate my aftermarket cooling fan (one single spd 12 volt) using the ecm's pwm signal. Thanks, Gary

While I have not personally done this, you should be able to max out the fan tables (to 100% values) to get the signal. With fan off, set the temperature values to 0%.
