Code Reader on 1990 Dodge Ramcharger

What brand of code reader can I buy for a 1990 Dodge Ram 150 Truck - and where is the plug? Thank You

I'm not sure where the plug is. You can probably find that information on the Autozone website.

You do need to make sure you get an OBD 1 reader, and not an OBD 2 reader. Cars made after 1996 are OBD 2, and it's a different plug.
