I have an older MSD 6M-2 box with no rev limiter installed. I would like to install a MSD 6M-2L with the built in rev limiter. Is the wiring plug & play between the 6M-2 and 6M-27?

Do a search on web for those 2 models wiring diagram and you will see how to wire and if any differences,

I have looked at the online manuals. They look identical. The pictures that MSD has on their website make them look different. Someone else has to have real experience with this.
