FYI - installed the Harley oil temp gauge BUT used the extra oil pan hole - had to use an adapter bushing. Worked like a charm. I wanted the Harley gauge (with the Harley wording) to match all my other gauges. But, had a real problem with the Harley install. One, they wanted you to cut the bottom oil supply hose out and somehow install a treaded nipple adapter in its place - while somehow getting the hose clamps installed - just seemed like too much work. Two, on top of that, they said you needed to toss the cover plate that covers those hoses. So for a $1.25 bushing I'm much happier. Installing into the extra drain plug whole does not seem as perminent as the orginal install. Since the Harley sensor uses two wires, I was able to put telfon tape and anti-sieze on the bushing adapter. Lastly, Harley wants you to remove the fuel tank (after purging the fuel pressure) - I was able to use a 12 gauge electrical wire (one of the coated wires abour 2 feet long) and fish the temp gauge wire through it. Since I had a Air Temp gauge - you're also able to use the orange wire (becomes the POS on the new oil temp gauge) and the black (GND) - i.e. no need as in the intructions to run those wires back to the fuse panel and grounding plate. One other piece of advice - the plug that was in my Ultra extra drain plug was put in with "red" loctite - make sure to either have a warm engine or in my case I heated the plug with a heat gun for about five minutes. Hope this helps.
