Never seen one of those connecters. Interesting. Yes alternator has been bypassed for quite awhile. I connected both wires from amp gauge with brass bolt and wrapped in electrical tape. It still looks good after a year or more; no melting. Thanks all.
That connector type is a crimp type, not a solder type but I do both on them for high current caring loads You will need a # 8 gauge wire crimper to crimp it properly
