Here's how to do one adjustment to your temp gauge for example:

If you set up your cluster on the bench just like this one with volt reg plugged in, apply 12v to the 2nd pin in from the right. attach one end of a jumper wire to the pin in that same row that goes with the gauge you want to adjust, say pink for the temp. clip the other end of that jumper to a Radio shack 271-1103 23 ohm resistor. attach a 2nd jumper to the other end of this resistor. you will have one end of one jumper hanging in the breeze at this point, run that end to ground.

at this point, you can use the little adjusters on the gauge to make it read 170 to 180. then change the resistors out for the other two settings and adjust the gauge according to the chart.

I found that the ones I did were either very close or way way off. there didn't seem to be a middle ground.
