BTW everyone, those gauges are real nice. They used to be mine (before I decided I wanted the playback capability of the Defi's I replaced 'em with). I built a real nice wiring harness and oil temp/pressure filter sandwich adapter. It's almost plug-n-play, save the splicing for +V/GND/Ill you need to do in one spot.
Hell, I might even be willing to buy the oil temp/pressure/water temp gauges and center pod back from ya, since I never got around to buying the Defi versions.
