Looking at the bottom of the '05 seats, there are a few connectors on the seat harness I am trying to determine what they are.

On the driver side there are two back plugs with 2 pins each. I have metered these to tell they are connected to the seat switches.

There is one red plug with two pins. This measures about 30 ohms across the pins, but from what I could tell was not attached to the seat switches?

There is one black plus with 4 pins in it. Two of them are continuous across the plug, and the other two are as well.

I need to know which wires are for the heated seats, which ones are for the seat belt switch, and also which ones (if there are any) are for occupant detection?

Any help would be appreciated.
