Wiring Question

Hi everyone. I am little embarrassed that I have to ask this question.

It has been a while since I have put any radios in to a mid 1990s fords so in my old age, I am forgetting how I used to do it in the late 80s early 90s.

I am putting an alpine in my 95 f250. My harness from metra (70-1770) has a dimmer wire and an illumination wire and my Alpine harness has an illumination wire. The description from alpine is making me think that the illumination wire really acts as a dimmer but I am not sure.

Which wire (dimmer ground or illumination) on the metra harness goes to the illumination wire on the alpine harness?

Thanks for any input you may have...

Keith

Most likely it will work on either. Hook it up to the dimmer wire if you want it to dim with your dash lights, if not then hook it up to the illumination wire.
