I am having the sme problems with my '95 Lowrider. Did you ever figure out what was the cause? I think I may need to replace my self cancelling module???

 

Hi Julioo and welcome to HDF from the UK. This is an old thread and difficult to read so I suggest you start a new topic and explain your problems more fully. It will save us reading back to 2008 and guessing!

 

The old lights were self grounding so only 2 wires. take the black wire from the new lights and go to ground. there's a screw on the triple tree you can use. then figure out which wires go to what for blinker and running lights.
