Ok so my brother gave me a MSD 6A ignition control module and a MSD coil. I wanna put it on my '66 mustang but i don't know it i should try to put it on. I have got 7mm Flamethrower wires with NGK plugs. My brothers attempt to install this ended tragically with his car on the flat bed of wrecker. Wouldn't stay running cuz the PCM thought the oil pressure was low.

 

Had that set up on my old 94 Dakota 5.2L and loved it. Just read the instructions and then re-read them. Then triple check your wiring and you should have no problems. I did leave my stock coil as back up which I needed one night when my blaster coil burned up.
