Yo George! BackNBlack! Don't leave a brother hangin' here! I need to know which red wire to tap into with that second diode. Everything else has been done! Thank you in advance!

Thanks. My main problem is that I see no long red wire from any connector. I've got the red and orange wires on each side that are tied together via resistors and the only other red wires I see are jumpers connecting the three boards to each other. One, off to one side, appears longer than the rest of them, but I don't get the connector reference at all so I'm not sure if I'm tapping into the correct one or not.

I've got two yellow and two white that are attached to the connector that the harness plugs into. The yellows go on the board near the word "stop".

Make sure of your diode orientation. The Cathode end should always be toward the wire with the resistors. Its not quite clear in my picture. An artist I am not.

Ugh. I got the diode orientation correct and just tried to power up my first completed lamp. No light at all. Not good. When I hit the brakes, the center cluster lights. But the halo is totally out...

You know, I took a different light out there and tried it again. Same result, but I tried reversing the plug and half the halo lit. ?!?!!?

What you CANNOT see in the pictures is the diode that is also connected to the white positive wire before it hits the resistored wires. Man, and I thought I was being very careful and tidy while I was doing all this stuff. I am totally bummed... While I await your reply, I'm going to try the other lights and see what they do. I'm assuming that I should be able to plug in one lamp at a time and test them that way...
Well, whatever I've done wrong, it seems fairly consistent, at least. Halos non functional - whether lights on or off. Brake center lights, functional. Could it be that I spliced into the wrong wire with that second diode? I went via your drawing, which was the lower of the two yellow wires I had. Maybe I should have spliced the other one. Maybe I'm sending ground to the red/orange wires that terminate to the resistors cluster.
I made the mistake of heat shrinking everything on the one that I finished, so for the sake of the photo, here is one that isn't finished yet, with the 2nd diode "resting" against where it would be soldered later.

Do you have a volt meter? Plug the light in the harness. Take the black lead of the volt meter and connect it to ground, you can use the ground strap that is located in the rear bumper by the antenna. Use the red lead to probe the two yellow wires while someone hits the brake pedal, let me know what voltage is present at each yellow wire.

I've got a volt meter, but it's going to take me awhile to be able to do this. I'll see if I can con one of my kids into helping me.
