ididit Retrofit Steering Column: 1970-74 Cuda/Challenger - Manual (Page 11)

There are a few aftermarket harnesses out there for this application. Some are a
direct factory replacement. Others are based on the GM wire color code. Our wire
code is GM based. If you get one of these kits we have matching connectors and
this may also plug directly in. Note that our turn signal plug is the 4 ¼ male plug.
If you have an aftermarket wiring harness, please resist the urge to cut the plug’s
off.
We have both male plugs and both female plugs in stock if you need one that was
not supplied with the kit. These plugs come with terminals, and instructions. If this
is the case for your installation please call us at (517) 424-0577.
