Arent these 12v auto connectors?

Butt connectors?

[Rollie Meyers]

They may or may not, but doubt they are listed for use with solid wire. I am not comfortable w/ those butt splices. Unless they have a UL or other NRTL on them I would consider them as a unlisted item (Automotive type).


Edit: Was the correct crimping tool used also??? (As spec'ed by the manufacturer).
