I have a 97 Z28 with OBD II, I am running a MSD 6BTM ignition box, and today I just bought the GM HEI MSD blaster coil. I am running the stock coil on my car now, with the GM harness 8877, I also own the 8876, but don't use it. Now, when I went to install the new coil, it says use the 8876, will it be a direct fit with my application? I'd imagine..but I just don't know yet.

 

thats what i used for my 97z
