I've asked some questions about wiring, LEDs, etc. in other posts, so I wanted to post some pictures of my completed pseudo-DRL project here. I was mostly going for something that would make me visible to other drivers, not necessarily for road illumination, so I wanted lights that would be on whenever the car is on. Zolitz's foglights were my primary inspiration, and he was even generous enough to sell me an extra pair of LEDs he had (thanks again!). I picked up a Buss "Add-a-line" at Advanced Auto Parts for about $6-7, which GREATLY simplified this project - I was not too excited about finding and splicing into some other switched power wire.

This product lets you keep an existing fuse in an occupied circuit, and add an extra with a wire coming out the top. The only switched fuse I could find in the engine compartment was for the EFI (the Add-a-Line was only good for 10 amps and under), so I went with that rather than pulling a new wire through the firewall. I would have preferred to tap into some non-critical accessory circuit, but I also wanted to keep this as simple as possible! The EFI circuit is still protected by the same amperage fuse, and the new double fuse + wire assembly still feels firmly attached, so I'm not too worried about it.

I then popped out the "fog light" panels in the bumper (not as easy as it sounds, with limited access from the rear), ran wire to each bumper hole, and color coded the ends so I knew which were which.

For the actual LED installation, I drilled out the bumper insert panels with a hole saw, and stuck the LEDs in at an angle that looked approximately forward-facing. I didn't worry too much about proper aiming, since I just wanted something that would be visible, and this can be adjusted later if I deem it necessary. The LED housings are held in place with two 4-40 bolts (that was the only size I could find that would go through the mounting holes on the LED body). I used hot glue to at least partially seal up any gaps around the LED, and this holds them in place a little better too. But even if the hot glue fails, the bolts should hold pretty well. I masked the reflector and front of the LED housing, and sprayed the whole thing front and back with flat black rusteoleum (mostly to slow down rust on the bolts, and also to hide the bolt heads).
Connected the wires, verified that they com on with the engine, and popped the panels back in place. All set!

I also installed a TRD anti-sway bar (from scionpartspeople.com - cheapest I could find online). This installation has been addressed here before, instructions are provided with the bar, and it is very straightforward, so I won't say much about that. But I'll post a few pictures that I think would have been helpful before I did mine:

Thanks for looking, and I'd welcome any comments or constructive criticism.
