ST205: Wiring up a DRL harness on accent/city lights, Not working so well Options

[Jeebus]

Well, I read through 36 pages of search results on wiring, so I tried wiring my lights up last night, and it didn't quite work.

First off, over the past week, I took off the plugs from the DRL unit since they don't fit onto my accent lights, and soldered female disconnect plugs on them, so that they can wedge onto the prongs on my accent light plugs.

I did some research on wiring for headlights, and figured most lights on Celicas have a negative wire that is White with black stripe. Here are the wires from my car, positive on top, negative on bottom:

High Beams:
Red
Red w/ white

Low Beams:
Red
White w/ black

Accent Lights:
Green
White w/ black

Front Turn Signals:
Green w/ yellow
white w/ black

Fog Lights:
Red
Black

So my dilemma begins. Here are the pics that I've gathered from the eBay listing, as well as what I'm trying to accomplish:







I wired the DRL unit wires (Red/Black) to the positive and negative terminals of the battery.

Plugged in my accent lights into the DRL unit.

I tapped the left yellow wire into the red wire of my left low beam light.
(I only tapped the yellow wire on the left side, as there was already a tap on the low beam left on from before, and I didn't want to tap the right side if this was going to be incorrect and leave exposed wiring after removing my errors)

The white wire, I didn't plug/tap into anything, as I'm still trying to figure out which exactly are my side/parking light. It has a male disconnect plug, which I assume I'll have to remove so that I can use the wire to tap into another wire.

So the accent lights came immediately on as soon as I attached the positive battery wire to the battery. They would not turn off no matter what I did. I tried moving the black grounding wire off of the negative terminal of the battery onto a bolt on the chassis, but the same result. They stay on as long as the battery is connected.

Next up, the left accent light that is tapped into the low beam. It stays on. I turn on the low beams, the accent light stays on. I turn on the high beam, the accent light stays on. When I turn off the low beams, the accent light turns off momentarily, but then turns back on. Perhaps I need to tap the yellow wire into the turn signal light?

I'm a little at a loss here, as I want to get this done myself instead of paying a mechanic $60~$80 on top of the safety inspection.

Thanks for the advice here folks. I looking up relays to piggy-back some power from, and was thinking relay #15 (Fuel pump), or the EFI relay, but I was discouraged once I unbolted the relay boxes and took a look under them for the wiring.

General consensus seems to be grabbing an ACC source from inside the cabin.

I went out and bought a 12v SPST relay with a harness, albeit a 5-pin one, so I'm going to need a little assistance as to the general wiring.

I drew up a diagram, but need confirmation as to whether it's correct. I probably need to add 15A or 30A inline fuse between the battery and relay, eh?



As for the power source to pin 85, it could be anything switched on when my key turns to ACC, correct? For example, if I decide to take Hugo's advice on grabbing ignition voltage from another relay.
