Plastic piece on the coin box?

Anyone with a big red mvs cab want to see about helping me figure out what used to be attached to the metal coin box in my cab? There's a plastic piece that's broken off, a matching sized hole on the other side of the box but nothing remaining there. If you know what I'm talking about help please

I'll have a pic up in a minute.

It's for a clip that holds the coin doors wiring..I only have one on the left side of the coin box.
.Thanks lithy..
I didn't even know that was there and the wire wasn't in it like it's supposed to be.

Thanks a bunch I had a suspicion it was a wiring clip but just wanted some confirmation.

Your welcome lithy..

I wonder if this piece can be purchased anywhere..
