Okay, so this will be a hard one for you all.

The ultra gauge runs off a OBD port. However my cars pre 1996 and does not run a OBD port. However I want something that will allow to to display multiple readings for things like oil temp, water temp, intake temp, and so on. Trouble is I don't want lots of gauges, want to try retain the standard dash setup.

How else can I do this without the OBD meter onto something like a ultra gauge / scan gauge
