It seems the new lamp harnesses have no way to connect to the car's connectors. these are from Autokrafters. The first 2 pictures show the lamp harness comes with some adapter. I figured I didn't need that because obviously I need a connector with 3 pins. why it's there to begin with I have no idea. Problem is the new connector will not fit into the car's. Pic 3 shows that the adapter wire will, but that cannot be right and no surprise the light does not light up. I do not have old connectors because everything was wired straight with electrical tape. It was bad.
I might be wrong but I think one is for sport lamps (hot and ground) and the other is for turn signals (2 hots and one ground).
Does your car have turn signals under the bumper or does it flash the grill lights? My lights have two hot wires going to it and the socket is for an 1157 dual-filament lamp. Ground is through the case to the radiator support. Take the bulb out and see if there are two contacts on the base.
Only One side was flashing before I ripped it all out, and those would be the lower yellow lights. Those are fine. I ended up having to shave down the damn new connectors with a razor blade all the way around tonight. Even then I had to force it. After Autokrafters tech got back to me, I informed him of the issue and promptly ignored it. This is the second new item that did not fit my car. The first one was the bezel nut for the Grabber sport mirrors.
