Is anyone familiar with hooking up a radio in a 1997 lincoln town car?

Question

I have a harness kit that has the rectangle plug and a square plug, but the square plug doesn't fit so none of my dash lights come on. Please help.

Know I hooked up the radio using just the rectangle plug, and the fuse is fine, are there any more suggests, thanx much for you info so far.

Answer 1

Of the two plugs, only the rectangular plug is required for an after-market radio. The square plug doesn't have to plug into anything. If you dash lights don't come on, check the fuse for your instrument panel illumination.
