I recently got some CSGs and the wiring on them has been a huge hassle. I have an AP1 and the housing are OEM AP2. I followed the thread with the ap2 conversion and I’ve done all the steps, however I still cannot figure out how to get my turn signal/reverse light to function. I’ve tried bending the pins and mix and matching the sockets. If anyone has an AP1 and wired their CSG to work fully, please give me some insight

 

The stock wiring is for incandescent lamps; polarity didn't matter when the car was built. I had the same issue when I swapped to LED bulbs. De-pin the connectors and switch the wires around; the LEDs are polarity sensitive.
