Read the sticky on TGO. It well covers them
Oil reuses the late model 3rd gen connector or the 4th gen unit. LSx oil sender works fine
Directly connect the tach to the PCM tach output wire and calibrate the PCM for 6 or 8 cyl operation depending on the cluster
Speedo is a direct connection from the PCM
Voltage meter is read off the overall system charge. No changes are required for this to function
Several options for temp. Modify the 3rd gen sensor to fit the LSx heads, drill/tap the LSx head for the 3rd gen sensor, or use a 98 Fbody temp sender combining the CTS and temp sender into one sensor. The 98 sender uses the same connector type as a TPS
