Speaking of guages - oil temp

[john42]

The thread on the useless clock reminded me. I have an oil temp gauge that used to be hooked to a sensor in my oil pan. Now after the engine swap I no longer have a sensor anywhere for my oil temp. What's an easy way to resolve this? I know they (oil temp gauges) are rarely accurate and to many a mechanic the bane of annoying questions from old fiddlefarts like me. I would like some reading on the gauge though even if I mostly ignore it. :-)

I should note there is not a bung in the oil pan for one. It's a brand new Ford Racing Boss 347.
