How To Install an Ignition Switch in 1970 Dodge Dart
Many reproduction switches have a extra smaller gauge black wire poked in a connector port where the factory poked the orange wire that goes to shift bezel illumination ( column shift, varies with model and/or build ). This extra wire isn't shown in above drawing, nor is what the factory did at the connector port shown as open.
To put it together as received will only blow a fuse. If you don't have the special tools required to remove terminals from connectors, go ahead and snip the orange wire. Make it up to the wire coming from that bulb socket beside the OEM connector. Male and female spade terminals or simple butt crimp. The extra black wire,,, just forget its there.
