Trigger wire for aux lights?

[DonFitzwater]

Can someone tell me which wire to tap into for use as a trigger for some aux driving lights I'll be installing on an 08 MegaCab? I picked up a set of Lightforce for my wifes truck and I'm concerned about tapping into the wrong wire and causing lighting issues due to stupidity. I picked up a harness and relay assembley and would like to wire it into the high beams. Thanks

I tapped into the high beam wire about 4 to 6" behind the left headlight connector.



On my truck, the wire is white/green, but yours may be different.

I'm not sure if this helps, but the diagram below is what I used for my backup lights. I'm sure they would work for your Lightforce lights as well. Please don't credit me for the diagram, I just altered an original design by another member to fit my lighting needs. I didn't want to tap into the existing wiring harness, due to the amount of problems that have been discussed on this site. If this helps and you want help, simply pm me and we can discuss the problem.



Good luck,



David

This is exactly what I did. Keep in mind that the passenger side is not wt/lg like the driver side, it is wt/lb. Your '08 colors may be different, but yes it works great.
