@Marshy unfortunately I have not seen a similar vehicle in today for pics.
This is the connector end view for the body side of the harness. You should be able to follow where it comes out of the seat cushion at the rear. Move seat up and forward for more access.
You will need to "mirror image" the element side connector to be sure you are checking the element portion.

Heres the terminals. Unfortunately the wires are all black on the element side, hence having to figure out by end view which to check.

Heres a generic exploded view of the seat. Im pointing to the element harness.

They no longer give a resistance value on these years, but on older ones I believe 2-4 ohms was good. Under, over or open is no good.
On another note, heres one where the customer complained of a vibration and lack of traction in snow..
