Were there any wires or thermocouple that came with this or connect to it? Also, the silver material on the right hand side has a yellowish tint to it, as if it were maybe colorized due to heat, or might be chromium over some other metal.

It's difficult to tell from the picture, maybe if you provide a few more someone can identify what you have there.

More pics As far as what they came out of I have no clue, how you see them is how I got em. I tried everyeverything to get the backing off but it seems impossible without breaking the board. If you guys do not see anything valuable then im going to toss them, they have caused me too much frustration already.
