Thanks for the input, when I looked on the parts microfiche it looked like part #21 which is a clamp, which I can't seem to find in the parts I have laid out on the bench, hence the question for the forum.
I didn't have a chance to look at it today but at this point I'm guessing it must be for a clamp connected to one of the wires I have tied up out of the way.
Anymore ideas?
Thanks
