Question: 1981 sensors and sending units

Does anyone have a diagram showing the various locations of all of the sensors and sending units on a 1981? Basically if anyone can tell me which units send signals to the gauges it would help alot. I have removed my A/C and A.I.R stuff and am putting a new exhaust on the car. In the process I have been snooping around quite a bit and have noticed a few sensors in pretty rough shape.

I can tell you that the gauges are independent of the computer system. The check engine light is the only part of the display that is tied to the ccc. As far as the location of the computer control sensors, a corvette shop manual is a must. Part no. st-364-81. I got mine on ebay for about $20. Pretty hard to tell if a sensor is operating by physical apperance. A sticker on the hood (drivers side) shows the routing of the hoses for the ccc. Hope this helps
