I need to know how to run a wire through the firewall for an aftermarket switch for LED spotlights. I just want the switch to be somewhere below the steering wheel. Any help is greatly appreciated!

This should help.

I used the grommet between the Brake booster and the ECU box.

My car is a V6 is that makes any difference.

I don't think it will.

I would expect LED spotlights to pull relatively little current.

If that's the case, the power you need is already on the relay plates, just above the headlight switch. There are studs for various power sources, e.g. constant power, switched with ignition, switched with ignition and load reduction relay, depending on when you want them on. You'd just need a ring terminal and your own fuse. The numbers and wire colors, or a quick test, will tell you which is which.
