im putting the 99 front end on my car. While connecting the turnsignal lights, the harness is not the same as you would immagine. I went to a junk yard for a few hours looking for a connector I could splice into the stock harness.
the old harness has wires that come out of the bulb sockets.
the new lights have a plug right on the socket itself.

How can I find this connector?
can I buy it? is it used in a mazda here in the states?

 

you do a little soldering job here and there (might have to hack off a bit of the plastic thiggy around the prongs on the bulb side) then you cover the connection with liquid electrical tape and voila!!

I did this to mine.

 

sounds good to me. I guess now I can stop looking for teh connectors
