Hi all. I have a '98 sierra 5.7. I already have a dual electric fan conversion on my truck with a in the cyl head thermo switch with a fender mounted relay.

I just got a GMT800 5.3 dual fan assy with the complete wiring and fan relay harness.

Can this be wired to the temp unit in the cyl head to make it turn on and off like it already does? Or is there away to intergate it in the black box computer?

Thanks for the reply. I did not see anything on how to make the gmt800 harness work on the gmt400 system. I already have an efan setup. I was just trying to make the gmt800 setup work or make it work on the setup I already have.
Oops! Old memory.
