"OP here: Someone asked about voltage -- this is 12 volt. And again, thanks for all of the advice."
I asked because the answer matters depending if high or low voltage. Yellow butt connects will work but INMO I would use a RED twist nut. Strip back wires 3/4" twist them together and turn the connector until tight and the wires start twisting. Once that is done i would wrap the connector and wires with good quality black electrical tape. They will be a strong and GOOD connection.
