Ok so how do you wire up the black wire from the c104 near the glovebox to the tach? I have an 84 eta and have found that the 87i harness I've used has the tach information in the blue/black wire on the 3pin c104 connector.
Question is....where do I run that blue/black wire to? I sold my obc harness with the green and yellow connectors which run into the back of the cluster....so do i need that harness back or is there a place i can connect the black wire to.
Also just run the green wire to something positive right?
