[QUOTE="Rednaxs60, post: 231836, member: 4617"] Looked into the tach issue, perused the electrical troubleshooting manual and the digital dash tach gets the signal from the ignition coils. I did not think this was the case because the travel computer (TC) has a wire going to the digital dash and the TC gets a fuel injector signal from injectors 1/3. It would seem that the injector signal to the TC is for the fuel management system. I will have to chase the wiring to determine what goes where. The digital dash tach has an input from the coils but each coil is pulsed twice per engine cycle. I have COP units and will have to wire the respective coils to match the required two pulses as if the system was still a wasted spark system. This is a diagram of my initial thoughts: [ATTACH]50927[/ATTACH] A diode will be required to restrict any cross signal between the coils. The first pic is the original ignition setup. The middle picture is what is presently installed - 4 COP units. The third picture is how I intend to connect to the OEM wiring to have a digital dash tach readout. [/QUOTE]
