headlight / parking light help

[aquillen]

I added info you asked for long ago about headlight relays managing the low & high modes for the single lamp in the new style. Hope it helps, but way late for sure.

And, dogonnit, it's probably different from what you already wired, and considering your wiring isn't working, I wouldn't be surprised.

About the parking lights, they are LED and so polarity sensitive. Maybe all you need to do is switch leads for that problem. Some LEDs will be burned out when wired backwards, but not always, and I don't know about specifically these. Verify they work with a battery or other 12V supply, not connected to anything in the car. And work out the polarity doing that as well, then wire appropriately.
