So as stated in the title im having the one issue that most people have when it comes to these harnesses. Well this is where my problem begins, so as most threads say online to take the spare terminal on the icm and and run a wire to the shock tower tach plug. as soon as i hook up the wire to the lonely blue tach wire on the tower it shuts off. if the car is running and i touch it to the blue tach wire the car shuts off. as soon as the wire is removed is starts up. its on the right terminal in the dizzy, everything is ran how its suppose to. i have 2 different obd1 ecus also both have the same return when used, there is no difference at all still no tach and as soon as the connection is made the car dies. this is in a 2000 civic ex coupe. any help would be great. thank you
