So I searched this forum yesterday for about 2 hours looking for this and found nothing. I need to know if my 98 cav has a positive or a negitive lead going to the horn. Thanks.
 
Horn Trigger	 black 	 - 	 steering column
negative
 
 
However, the actual wire on the horn is a positive lead.  I mean the horn under the hood.  The one that makes all the noise.
