map light hook up

I have a map light with the harness from a 72 Valiant. Badlilred looked at his 72 Duster and seen where it hooks up above the glove box, in the steering column and over by the headlight switch. I am putting it in my 71 Duster. I started by the glove box and cannot find any jacks to plug into. Any help would be great. Thanks.
