BE CARE-FULL!!
why do you want to hook it into a msd box?
Call Mallory and talk to a tec the distributor's are very sensitive and if you use the wrong ignition box/coil it will damage your distributor.
For my Mallory the instructions and the technician are very specific on coils and ignition boxes and wiring procedures.
You can always go to the Mallory web page or summit and see about down loading instructions.
I have the Mallory comp ss electronic pick up distributor and the directions where very specific on-to what and how it was hooked up!
my recommendation to you is get a..
Mallory Ignition 29450 - Mallory Promaster Classic Series Coils.
all it needs is a hot ignition wire and that's it no ballast resistor.
And if i'm not mistaken i think multi-spark ignition modulus don't even start multi-spark-en until high rpm anyways.
But what ever you do do it right and good luck!
keep us posted also.

My understanding is the multiple spark is for 20 degrees of crank rotation and ends somewhere around 3500rpm, the coil field would never support multiple sparks at higher rpm. Also, I don't know what the third wire does, but I would meter it out. My theory is that it is common to ground, designed for early distributor fiber gaskets instead of an o-ring.

RED= positive
GREEN= negative
BROWN=ground
ignition hot to coil coil harness pos. neg. grnd. too dist. harness, ground to block/manifold
i installed a Mallory circuit guard between coil and dist.
i don't know much about multi. spark systems
but i know i need a nice long hot spark i get that with my set up
UPC:769105119313
Coil Wire Attachment:Male/HEI
Coil Style:Canister
Primary Resistance:1.400 ohms
Coil Internal Construction:Oil-filled
Coil Color:Black
Maximum Voltage:55,000 V
Turns Ratio:105:1
Secondary Resistance:12.3K ohms
Inductance:7.3 mH
Peak Current:95 mA
Spark Duration:500 uS

E-mag/P-mag user here, I'm not too impressed with the aircraft E.I. that are out there (p-mag is okay and getting better) but..... how many times has your electronic ignition in your automobile failed while in operation? My answer to that question was/is ....never, oh I've had a couple of failures but not while driving, I've also have (usually) had advanced warning that something was/is wrong. There are some great choices for DIY aircraft electronic ignitions, the Megajolt with the Ford edis parts is a favorite of many hotrodders with reliable results, I intend on using that system coupled with a P-mag on my current aircraft, the future of E.I. in experimentals is promising. Oh and for what it's worth Slick mags are pretty junky now-a-days and require the 500 hr inspection/overhaul at way too much costs for old tech.

i suppose there are a lot of differences but allot of similarities between magneto ignition system's for car's and plane's
as far as and electronic ignition failing i have never had one fail on me
But with that said i purchased pertronix ignition system, the halo pick up system and i went through 3 of em in about 6 wk's
the first one failed as soon as we installed it the second failed after a 20 minute run down the highway and the last failed a week after it was installed
my Mallory is running fine i've got a few post's around here about it.
