Overriding heated seats

[6768chevylover]

I know the light blue wire is the heated seat wire for the Tahoe seats but I seam to have 3 light blue wires on my driver seat and 4 on my passenger seat. This is on the pigtail going into the seat plug. I think I might of narrowed it down to the one wire that is to be used. My questions are, Is it possible for the module to prevent the seat from heating up? If so, How do I override the module to see if they work? I have no idea what wires along the seat are for the heated seat wires... Thanks, Mike
