Does Harley or anyone make a pigtail plug to plug into the Acc switch harness under the seat?

I want to use the Acc switch to turn on LED under lighting.

 

If you can't find one goto your local harley dealer and get the components to make one yourself. Use the following website to find the individual part numbers:

It will probably only be a few dollars in parts.
