MSD BTM install

[psicvc]

I just bought a used msd btm unit part number 8762. Little did I know that this is the btm designated for msd ignition boxes. I dont have an msd ignition. How do I install this to my stock ignition? There are red(power), black(ground), a yellow and a white wire coming out of the unit. I know that the yellow or white goes to the negative side of the ignition coil, but which one? And where would the leftover wire go?

I think your best bet would be to call the MSD tech line, they're very helpful, too bad its not a 800 line, so you have to pay for the call. If your btm for msd ignition doesn't work out, i have one for a stock ignition for sale. Used only 2 months, so its in pretty good condition.
