Can Anyone Identify this Piece?

[Ed Salsbury]

Hi Guys,
I found this piece under my car tonight. Can anyone tell me what it is? Car runs okay but

is still hesitating like crazy, just waiting for my Scanmaster to come in.
Thanks
Ed

Does it still start okay? Cause that's the end of your starter solenoid

As in kicking back on start up?
