Which gauge? The oil pressure gauge? Doesn't your '89 block have a 3/8" NPT plug above the oil filter like the earlier blocks have?

You will have typ use sensors that are correct for your year car. The 89 sensors will not work.

If you need help, you are going need to be more specific. Which gauge(s) are you having trouble with? What kind of trouble are you having? What is your problem? I have a 2001 L31 with TPI in my 77. The gauges work without a problem
