Alright, I need some help fellas.

I have a 5.3 in a 92 fullsize.

I have added a single electric fan.
I have it connected to what I understand to be the high speed fan signal (red connector #33)
Also from what I can tell the fan should come on at 200 and off at 195.

I also had the a/c wired to kick the fan on when the compressor was engaged, but I am getting nothing.

Anybody have any ideas.


I have a 75amp relay with 12 volts entering pole 30
87 to the fan
86 to a ignition on 12 volt source
85 pin 33 red connector on the pcm.

Any ideas why this isn't working.
