Trigger wiring for LED light bar?

I've looked but haven't found anything...so I figure I'll post the question

On older vehicles when I add aux lights, I simply tap a high-beam wire to trigger a relay, to turn on the aux lights with the high beams. Typically I will put a switch in line with that trigger wire, in the cockpit, so I can override-off the lights if needed.

I want to add a 12" single row LED light bar to my Summit (factory HID headlights).

1 - IS there a high-beam wire that can be tapped?

2 - if I tap said wire, will it piss off the computers and throw some sort of trouble code because of the added resistance/draw/etc?

My plan is to use a trigger wire to a switch (the cockpit override switch), and from there to a normally open relay. Power the relay from battery. Turn on the high beams, the trigger wire goes hot, closes the relay, and allows battery power to the light bar. Technically all the "power" for the lights will come direct from the battery...I just don't know if the trigger wire will annoy the computers enough to cause problems.

Thoughts?

There is a white wire with a green stripe running to the high beams. That is the trigger! Vampire tap it and you should be straight

Re: Trigger wiring for LED light bar?

OK, I'm going to guess you typo'd it in this thread and it should be white/GRAY...

That said, is this for HID? My Summit has HID, not halogen, and I see different wires in the listing in your other post that say "Right - HID lamp driver" (pins 1 and 11).

Just trying to figure it all out before I go tapping wires and poking holes in stuff if I don't have to

White/green is the left hand driver, white/grey is the right hand driver. HID lights.
