I tried doing the LED foglight mod and got 50% success. The blown foglight emblem lights up blue, but now my indicator doesn't work.. I used this picture from JP7
And didn't get it to work. I used a red 5mm led inside and sanded it down to fit. But the spring doesn't exactly work inside so maybe that's my problem. And I thought that you wanted the negative side of the LED to be wired to the resistor?
It doesn't matter which side you wire the resister onto the LED, just that the polarity is right. I think if you're using the stock resister, you have to have the positive up to it (so that the polarity is right).
