Incorrect Wire Gage
Connector is preteriminated into 12 AWG stranded wire. Included crimp barrels are made for 14 AWG wire; thus, the 12 AWG wire does not enter the barrel. Vehicle uses 14 AWG wire for its HVAC blower power. Trimming down the wire diameter is against IPC 620 standards and is unsafe. This product needs redesign.
Bottom Line No, I would not recommend to a friend
