LUMINATOR Posted March 28, 2015 Report Share Posted March 28, 2015 Has anyone on the forum installed accessory gauges? I have a Sunpro triple gauge kit that I want to put in my 1990 Lumina. It has water temp, volts and oil pressure gauges. If anyone has installed these before let me know. It looks like a pain ! Quote Link to comment Share on other sites More sharing options...
RobertISaar Posted March 28, 2015 Report Share Posted March 28, 2015 you could get most, if not all of those functions by swapping to something other than the base cluster. I believe with the luminas, a 5 guage setup was on top? Quote Link to comment Share on other sites More sharing options...

GM believed that there were too many complaints of oil pressure variations, so the oil pressure gauge was removed and a voltmeter installed instead for the '93 model year.

RobertISaar Posted April 1, 2015 Report Share Posted April 1, 2015 seeing how GM did just that for 92/93 grand prix, cutlass supreme by using either a dummy guage/switch or a label-free oil guage, I'd say that's reasonable to assume even if there weren't factory documentation of such.

pwmin Posted April 2, 2015 Report Share Posted April 2, 2015 none of those gauges should be hard to install unless it didn't come with oil pressure. I put trans temp and voltage gauges in my 96 GP and it was easy. There should always be a water temp sensor, so you should be able to hook into that. Voltage should be easy, too. I'm not an expert on what options Luminas had, though. Quote Link to comment Share on other sites More sharing options...

I didn't know what that cutoff or distinction was between them, despite owning a 91 and a 92. Quote Link to comment Share on other sites More sharing options...
