Electric fans

[Twiz]

2001 GMC 2500hd, 6.0. Had a radiator leak not to long ago, decided to buy a kit, rad, fans, shroud, some electrical to make it work. I definitely had to do some rigging to make it work until I could buy other things I need to finish the install.

It came with its own temp sensor that completes the ground circuit, this activating the fans. Question is, are their any plugged ports somewhere that I can replace with the sensor? Or is there a way to wire the ground into the existing coolant temp circuit?

Thanks everyone.
