now.. i know that the TBI motor has a 2 connector coil...and i found the red battery wire and the white tach wire...but when i plug in the tach wire it my tach doesnt work...i have a HEI accel supercoil...and i can get the damn thing to work...thats the only flaw thats holding my car back in a way...i also have a MSD 6 AL ign system...what do i have to do to make my tach work???....
