Bag 3013-1 Wing Kit

Doing My inventory on the RV 14 wing kit

In bag 3013 (stall warning electric)
there are 2 wire connectors they look identical but the inventory calls for one #18-22wire/#8 ring
and one #18-22wire/AN3 ring

Is there a difference? How can I tell?

They look like the round connectors on Fig 2 page 17-07 (Part of the W400 assembly)

they both have 22-18 stamped on them.

Suggest you check fit of #8 screw vs AN3 bolt in the rings - that's probably the intended difference but you may have accidentally gotten two of the same, but if not only one will fit the AN3 bolt.
