Here's how I have it wired as of now:

30= BATT +
85= PCM PIN E3
86= BATT +
87= FAN

This IS different from the way the wiring is listed in the .doc included with the efan control patch for the 7427
Pin 85 is listed as Ground high amperage and Pin 86 is to PCM.



With the relay wired the first way I listed, I got the fan to come on instantly with startup with the enable and disable temps set to 70.7 and 60.4 respectively.

I then burned another chip with the temp on set to 284 and temp off set to 282.7 and the fan didn't come on (cold/warm started in driveway on both tests)
