The tach works off of an output from the GM PCM and hooks up to the tach just like the m30 did. There is some reprogramming needed on the PCM side but it is easy to do in HP Tuners.
For the coolant gauge I use the m30 coolant sensor and re thread it from m14 down to m12 in a lathe and put it in the plugged port in the passenger side head coolant passage. GM drivers and passenger side heads are both the same....just flipped from side to side.
The speedo is covered above...
The oil pressure gauge uses a s10 pressure switch in the stock GM location with a m16 to NPT adapter I get from summitracing.
I will also add a CEL light in the cluster as the e12 did not have one. There are a couple open spots to add a light.
I think that covers it. Let me know if you have more questions. Feel free to post, PM, or email me jake@classicdaily.net
thanks
