If so, be sure to insulate and/or secure the ends if they're hot.  My 
BJ8 harness came with a brown lead for a cigar lighter, which I believe 
was an option (my car doesn't have one).  Shortly after installation, it 
somehow touched ground, even though it had one of the metal/rubber 
'barrel type' connectors on the end, and it let the smoke out of a 
section of that wire in the harness. Surprisingly, the harness has 
otherwise been fine for, oh, thirty years or so.
