I have installed some modify parts to ignition system.
Final modify is MSD6A but I wondered where set up this.
Mr. Tom Keliher showed nice photo what installed MSD6A.
Ok, I installed new MSD6A, that I bought from my friend.
If your f-body has a external and dual connector type coil,
I'll recommend get the MSD cable harness(P/N 8876).
It is very easy to install MSD module. But I couldn't get it, because I'm living in Japan....
So I converted the wire of ACCEL super coil.
Installation instructions of MSD module is kindly to you install MSD module.
After installed MSD6A, my engine is good!!
