Thread: Let's Talk About Ignition Systems (Big Juice applications)

They are both good systems. The only reason I ended up using the MSD is, that's what we used on our SCCA 510s back in the day and never had any problems so I stuck with what I know. That's the same reason I ended up with a Sentra instead of a Honda. Nissans have been in my family before I was in my family. It's just a matter of preference.

if you were listening to me when i sold you the car you would have heard me say that the computer has no rev cut. and that is what the 6AL is for.

look at this

Its simple on the older cars with external coils.
Use your multimeter to figure out which wire is ignition switched, and the other one is your trigger. Give the msd box power and ground, and you're done.

its really simple. I used a oem fan plug like miko suggested and soldered it into the msd harness. Then plugged into the factory coil harness for the coil signal and 12volt switched signal. I will post up the link to the instructions when I get home.
