So once more I have run out of ideas how to get my tacho to work. For those who have no idea what I am talking about, here is a recap. I installed a silvertop 4age engine into my 1995 corolla, running on Wolf 3D ecu so the factory ecu is gone.
I have tried to connect the IG- to everything that could give of a signal for the tacho and nothing works. There is also noting wrong with power and earth connection so it must be the ig- signal.
I have noticed that the orginal signal wire from the 4EFE distributor is not the same color as the IG- signal wire that goes to the tacho so my guess is that the signal passes through the orginal ecu. Can this be the case?
