Seriously this isn't really DIY material.. It's easy enough to do if you have the connectors, and if you can't figure it out at that point you have no business doing it
Plug coils into wiring harness.. Plug coils into plugs.. Done

mars: you are the man.
i was thinking of something like this but was not very familiar with MSD products...
and i knew there must've been a way. since all DIS system have to work off some fundamental basics... but again, i'm not familiar with MSDs yet and this being my first distributorless car.
BUT, i had a another idea. not sure if cnnmnscnapps was already throwing it out there. but ok, say if it can be kept "reversible", and fabricating a kit to make it so.
like: stock 3 pin female connector--> stock 3 pin male connector(sourced from mazda??) --> wired to D58...1? MSD male connector--> then to the MSD coils
all using a thicker gauge wire of course... any negative affects you can think of?
and does MSD state the primary-secondary winding ratios for its 8247?
good goin on the MPG save! plan to do this kinda mod of some sort when i get up close to 24-30k miles.
thoughts? thanks

I'm waiting for four D581 plug connectors to arrive so I can fabricate plugs for MSDs and splice into the OEM coil wires. Once installed I’ll take the car for a spin and will update the thread with pictures. I hope to have everything installed by the end of the week pending arrival of the D581 plug connectors. 

good job on finding an alternative for those to consider on an ignition upgrade. better yet even an "multi-spark diacharge". i have always heard good things about this brand, and seen demonstrations in auto classes. i'm yet to try this brand and perhaps liking it... or even loving it.
sure would like to know your continued study on fuel savings and what ur MPG gains are.
much appreciate it,

When I did my LS2 installation (upon which this MSD installation is based), CRH started sourcing the materials needed to make this a kit, rather than a DIY.
He should have a bit of good news on that in the very near future.

Is your kit going to be setup for the MSD coils? As I understand it, they are wider than the OEM LS2 coils.
DIY mite be the way to go

Fabricating mounting brackets are my concern. I don't have access to the materials to do the job which will meet my own quality standards. Wiring isn't an issue for me.



Like THAT doesn't put pressure on us.
I am sending a bunch of parts to my source tomorrow.
