Thanks guys! I ordered that module from Bakereletronix for the tach, drilled out the adapter above the oil filter for the oil sender which is now working, had to order the 98 camaro water temp sender no one in the area stocked it. Special Thanks to Redheartbeat took all your advice. Problem I have run into is the speedo from 88 to 91 have the VSS buffer built in the cluster, both wires from the VSS run directly into it. does anyone make a converter from the pcm output for this ?
