MSD 6A/6AL Wiring Diagram - 1996 Mazda KL V6 (Ford Probe GT) Failed OEM Ignitor

This is a color wiring diagram showing how to install an MSD 6A/6AL ignition box on a 1996 Mazda KL-series V-6 engine when the OEM ignitor has failed, using an external coil. The diagram, credited to Eric Leska ([email protected]), maps the vehicle harness connector wires to the distributor connectors (distributor based on model #TOT57271), an NPN 3055 transistor (with G, C, E pins), a 1K 1/2-watt resistor, the MSD 6A(AL) box, an external coil, and the battery. A key-wires legend identifies the 12V ignition wire, ground wires, and the 5V PCM pulse wire by color. A note warns that on Mazda/Ford vehicles from other years, installers should check wire voltages before starting, since some wire positions may have been changed or removed. One distributor connector position is marked empty, and several wires are shown terminated/unused (marked with X). A reader can learn the overall wiring path from the factory harness through the transistor/resistor trigger circuit into the MSD box and coil, though individual wire colors are conveyed graphically rather than as text.
