I've searched the web and this site for answers but can't find exactly what I need.

After my battery died I found out it was the charging system. I diagnosed it according to the shop manual and advice on this site, and came up with the voltage regulator. I ordered what I thought was the correct part from St. Paul HD. Says it's good for 2003-2007 and I have a 2005 so all good.

The part came in and the connectors are different. Not a problem, I can rewire it, but then I noticed there's only 4 wires on the new part, vs 5 on my old one.




Does anyone have advice on how to wire this in? Or do I have the wrong part? Thanks in advance for any advice.
