Welcome to Allpar. Following the installation instructions, the Vt and Gn (twisted pair) trigger wires are used for a magnetic pickup distributor or crank trigger. The Hall-effect pickup in the Chrysler 4-cylinder distributor is not a magnetic trigger and may not work with the MSD. You can try it, but I don't think that it will work.
The instructions mention an MSD distributor or crank trigger. There is a hole in the transaxle bell-housing for a magnetic timing test probe used for a Chrysler special tool. A single Wt wire is used by the MSD for points-type distributors.
They also show a separate timing control module. Without this you may not have spark advance. You may want to contact www.msdignition.com for guidance on what you are trying to make work. I only see V8 distributor applications listed on their website.
Was it hooked up by the previous owner or just came with the car?

The instructions show a thick black wire (ground) and a thinner black wire (coil -).
The instructions don't mention a Bk/Wt stripe wire (could that be the points-to-ground wire?) or is it part of the Chrysler harness to the coil (-) or the 3-wire Chrysler distributor pickup?
There is a Bk/Gy off of the Timing Control Module.
