Just installed elec fans and harness out of a 05 Silverado into my 03 suburban and just want to make sure I wire it up correctly. Also if someone can guide me in the direction I need to go to get them activated I would really appreciate it. Fans and harness bot installed with no problems and in the factory location.

 

I can't say if you wired everything correctly, there are vids on YouTube that cover it tho. I do know you will either have to get the dealership or auto shop with tuning capabilities to set your ECU to read/enable the new electric fans.

 

You need to have your PCM tuned to activate them. Many vendors offer this sort of thing, but I recommend Atomic Performance who is a vendor on this forum
