Hi, I recently retrofitted a headlight that has been converted from a non-lighting package halogen headlamp to an LED intelligent lighting system.
So far, everything works fine, but there is one problem. When I turned on the locator light, it turned on including the side mirror light and the tail light, and the LED of the headlight did not turn on.

When I went to the repair shop, the man added two wires to No. 229 (7.5A front left headlight) and No. 231 (7.5A front light headlight). And the front headlight LED was turned on. However, the illuminated star emblem should be lit when the low beam is turned on, but it was turned on with an LED headlight, even though the engine was turned off.

Do anybody has idea to fix this problem?

That looks dangerous. Buy the correct wiring harness for the job. Do not mess around with the electrical system on these cars. They are not like a 1970 Chevy

Thanks for reply.
The headlights works without those wires, so is it okay to take out those wires? I don’t know anything about those fuse system.

Yes whatever they are there for they shouldn’t be. I would definitely remove them.

I removed those wires. Thanks! However the welcome light of LED are not working.. when I unlock or open the door.

Before removing those wires, I would be inclined to ask the person who added the wires what they are for/why they are necessary. If you have not done a thorough test of all the functions (front and rear lights), you may be missing something.

The reason why those wires added is those LED does not turn it on when doors are unlock or open.. it worked before those wires connected some fuse (I don’t know which one) but the problem was the illuminated emblem never turn back off… I am still look for answer

You can buy the illuminated emblem harness from the dealer. It’s a much safer way of going about it.
