where is that link to how to hook up a msd to duraspark

MSD cable adapter 8869. This plugs into the duraspark harness right to the MSD box, you do not have to use the white trigger wire on the MSD.

+1 on that adapter cable. I have MSD boxes on three Fords, all with that cable, works like a charm!
mine is or was a single 9 prong plug, i cut it and am just going to sod it together, however on mine, the instructions on msd.com say that there is a white wire used as a trigger, i have a white wire but its for the tach out and i also have a brown wire that the insructions dont even mention. so what is the brown wire :?:
 
Ari,

With the DSII, you need a control module of some sort. Either a GM module, or something like and MSD box. MSD is more performance by multispark at low RPMS (it goes to single above 3k RPM or something like that) which helps produce a more complete burn = more available power at a given RPM and more efficiency. The spark is no hotter, as that's a function of the coil.

Not entirely true- the MSD is a capacitive discharge system that controls the + voltage to the coil, so instead of 12V going to the coil in an inductive OEM system, the MSD pulses the coil with 420-480 volts, then the coil multiplies that for the spark. Starting with 450V instead of 12V gives you a hotter spark and if you've ever watched a CD-based ignition spark a plug you can even SEE the difference. This is also why so many people get confused when trying to troubleshoot a MSD system that is having troubles, they put a voltmeter on the + side of the coil and expect to see 12V+, actually you will see much more than that but only when the system is running, not just because the ignition key is on.

All that said, the multiple spark at lower RPMs is what I think is primarily responsible for really smoothing out the idle and low end operation of every engine I have put one on. I've tried other Capacitive Discharge-based systems, but only the multi-spark systems really smooth the engines out and increase lower end responsiveness like that.
