Hey guys, I just got done wiring up the Hella auxiliary lights on my Tracker.  Anyone who has worked on the lighting system of these things knows that they have a strange switching design.  I guess the lights are switched by the grounds, etc.  I can't claim to really understand it and I haven't taken the time to figure it out.  Anyways, the design of the switching makes it a bit more difficult to hook up auxiliary lights so that they're switched on and off with the high beams.
I searched around and I couldn't find a solution to this.  My slow internet makes it tough to search, so maybe this is already common knowledge.  Maybe not.  So I figured out a way to wire up the lights like this.  I did mine with the wires behind the instrument cluster since I wanted to minimize the underhood wiring, but it could probably be done under the hood at the headlight wires as well.  I took out my instrument cluster and found the bulb for the high beam indicator on the back.  I traced the two printed contacts for this bulb back to the wiring harness that plugs into the cluster.  I forget the colors of the wires that it ended up being (I'm pretty sure that one was red, and the other was the one right next to it.  White and blue, maybe?), regardless, it's easy to look and see the two wires that you need.  Then all I did was splice the trigger and ground wires from my aux. light relay into these wires using Scotchlocks.  It shouldn't matter which wire goes where.  Just put the relay ground wire on one harness wire and the relay trigger wire on the other.  This will do it.  The auxiliary lights will come on with the high beams and go off when you switch to low beams.  I could get into some of the electrical theory, but that would be boring.  Hopefully this helps out.
