98 Driving Lights question - wiring

[bergeron37]

I posted this in an old thread but I think it may have been lost. I am installing the dealer-optioned driving/fog lights on my 98. I was able to find them on ebay a few weeks ago and came with everything (lights, relay, fuse, toyota switch, and wires already connected) taken right out of another runner.

My question is this: I have a amplifier installed and the shop that did the installation wired it directly to the fusebox as in the picture below. Can I use this for my power source for the lights as well and put the two on the same connection? It would make for a much cleaner installation than going directly to the battery as in this write-up which is I have been using: 4Runners.org - Installing Hella 500 Driving Lights

Also I plan on grounding it in the spot indicated in the second picture. Thoughts? Nothing is hooked up as of yet but I just put the screw in there and what not to show what I meant.

Nothing? I have these hooked up straight to the battery right now and am not getting any light.

You can't just keep adding wiring onto some terminal on a fuse box. That terminal will support some limited amount of current drain before it fails.
Every wire in the vehicle is sized to carry what's connected to it and little more.
That's why connecting add-ons straight to the battery is preferred.

That's what I figured. There must be a short somewhere because I have it connected straight to the battery and am getting nothing. I'll have to tear it down and re-check everything again I guess. Pain in my ass.

Thanks for the response
