E-Fan tuning problem

Ok, so I bought some LS1 fans at a swap meet. Just built my own three relay harness, it works if you ground everything indivdually. The AC clutch works fine, however Pin 42 on the blue connector is always grounded?
So my question is what settings do I set in HP tuners? I enabled Fans and selected 2 Fans and set the on and off temps, but with a voltmeter on it 42 seems always grounded. What am I doing wrong? Should I change it to AUX fans?

EDIT --- OMG I just found another schematic and that one use Pin 43 instead of 42? I'm gonna pass out if that is true.

Tom

Yeah, we posted a few schematics to build your own fan harness a while back. :thumb:

and if you are using two fans there is another pin to engage for
the second fan.
pin blue 42 is the low speed cooling fan relay
pin green 33 is the high speed cooling fan relay
blue 43 is the #7 injector control circuit

Ok the link you show for the PCM has 80 pins, my Pin 42 is on the second row.

I know I got the right one, just not sure what settings in HP if they are right.

Ok, I actually loaded the pin 42 with the relay and it went to a few millivolts and start switching the fans on and off with HP Tuners and they it works.

What does everyone use for fan settings? Oh I have a stock stat BTW.

Thanks Tom
