Random wire unplugged under dash what is it where does it go?

Yes the lighter works. Not sure what TCS is. The green wire does route back to the lighter and is apparently used to tie into the dash lights so that it can illuminate with them. Comes on reproduction units like 68orangesunshine said above. I don't believe Blazers were available with illuminated cigar lighters. In fact I don't know what they would have come on as I've never seen an original one.
