No engine power when headlights on!

Ok, I just drove about 40 miles and there is a serious issue with my 2012 Z (2600 miles).

To be fully candid, I wired up my rear foglight yesterday without seemingly any issues. I wired it based on the write-up I did just today in THIS thread.

Anyway. Without the lights on, the car feels normal. When the headlights come on either manually or in the Auto position, there is no power. When I say no power, I'm talking about the amount of power the car has when the traction control kicks in. Just enough to crawl.

After about 10 minutes of driving this way, both the traction loss light and the ABS light came on. I thought to myself "ok, I'll just hit the button to turn off traction control". Well, this turned on the light that sad TC was off, but there was no different result.

Is there any way my foglight install could cause this? I tapped into the green (tail light) and red(brake light) wires from the left tail-light. Grounded to the consolidated ground just in front of that tail-light. The foglight works normal. No dimming of either the foglight or taillight. All connections were soldered and heat shrink tubing applied. All wires were taped in bundles and put in split loom which was further taped end to end. There is no way anything is shorting.

Tomorrow morning I plan to try just removing the bulb from the foglight and seeing if this solves the problem. This is the easiest way I can think of replicating my pre-install state.

I won't have any time to deal with this tonight, but I would really appreciate some feedback on how to jump into this. Or perhaps if there is another known issue.
