I have a functioning tach amplifier to fit into the diagnostic plug with input from the front of the crankshaft (not the flywheel at the rear). But with the transmission from the 1983 300D, is there a way to even attach a flywheel sensor and would that even be desirable? I don't have the data coming in from the EGR system and the turbo anymore. The way I figured getting around this was to "convert" the system to a 1983 set up, simpler. So how would I connect the tach amplifier from the diagnostic plug up so that it feeds input to the tachometer on the dash and what modifications, if any, to the climate control system are needed?
