Tach hook-up

Does anyone know what wire to hook the tach to on the distributor? I have an 89 Civic h/b with a DOHC ZC. Thanks. :frog:

under your cluster hood there should be two blue wires, its one of them...that wire goes to your ignitor in the distributor so thats how you check which one it is...
