If the driver side doesnt have wires sticking out like the passenger side as depicted in the picture, then what you see on the passenger side is part of the OC3 occupancy detection mat, which in this case won't be useful or working in your honda.
I'll look at those numbers, and if that production date is correct then those would typically belong on a E83 X3
if that is the case, as mentioned before the heating elements are intergrated with the vinyl or leather seat cover. While it is possibly there, you are lacking the control units and electrical for activation. I'll try to trace and ident those numbers you posted and will get back to you.
