Ok I have a 87 2.3 turbo motor im putting in my 79 mustang. I dont know what to do about the old ignition system Or how to hook up the new TFI ignition to the mustang

you are going to have to get the EEC harness for that.

I have the new harnessfro the new motor but the msd ignition hooks right up to the distribitor and the new TFI distribitor wirs up to the ECU because its computerized timing.
