Aux gauge lighting / wiring to allow for dimming

Finally got my Isspro tach, boost, pyro and trans temp gauges. Did a search, and got too many hits to review them all for my specific question, so here goes:

I want to wire the gauges so they can be dimmed at night using the factory headlamp switch (like the factory dash lights). Can't recall where I picked this info up, but can I just splice into the orange wire in the factory tach plug (I think that's the correct one for the lights) and run all 4 gauges off of this single wire, or am I asking for trouble? I know little about wiring, so I don't want to do something dumb and melt something - but then again, it seems these gauges can't draw much either. Any better/safer ideas or is this pretty typical?
