3.9mm or 3.5mm I need to make some extensions for an 1800 ligjt bar.going on a 1300. The normal ones u find in stores are to large
3.5 is what fits up to my '03 1800s. I don't know if they ever changed.
I used cycleterminal.com and was happy with what I got.
I just recently replaced my hand controls and installed HD passing/turn signal lights and used these with good luck. I even added contacts to the OEM 9P and 6P connectors for my projects and they were drop-in replacements.
THANKS Ladies and Gentlemen.. I woke up at 4am thinkin about it and just said hell its not my bike lol
cut and solder and shrink tube. workin like a charm now... If his bike was sitting all weekend in my garage
id never heard the end of it lol.
