Hey guys- pinball lover since the 70's, started collecting earlier this year. Picked up a Night Rider and someone hacked the connector on the transformer. They soldered one wire to the pin on the transformer. My question is, how do I know what size this connector is? I see a few choices and want to order the correct one. Also- does anyone send these pre wired-or will I need to transfer good pins and re-pin hacked wire into new connector (I work for Ford and we sell pre-wired connectors with butt connectors-so just wondering). TIA
