03 sierra E-Fans
Ok put in a two pin harness last night. Using the blue 42 pin and green 33 pin. The harness works because I can trigger it using a grounded wire. However the fans wont turn on at all when the truck is running. Can someone look at the tune and see if there is anything wrong or any other thoughts?
Im hoping its something stupid.

Beyond some different timing values, a/c pressure values and temp settings it's more or less how my 05 is set up. My fans work like a charm.
I just did a segment swap from an 05 1/2 ton and tweaked the temps for my trucks factory 186 t-stat.

Our turn on and turn off temps are close but your settings for A/C are very high. My high fans are set at 220F and yours are at 290F. So If you had the air running they would never turn on.
