Yes, what it does is the pulse changes polarity (if it goes first neg, then pos, it flops with the pos first and neg last) Only one polarity of the complete pulse triggers the box so if it flips this changes the timing in relation to the pickup and the contacts in the cap, so the spark "moves over" and fires BETWEEN the cap contacts
There is a YouTube movie or two about this....... Just be aware, and if it runs rough, "suspect." The MSD video talks about an adjustable rotor. In this case we are only talking abour reversing the pickup wires
Funny, I actually watched that when you told me to google it! I’ll make sure to inspect those connections if it feels rough. I might just use crimp connectors to test it out and make sure the pulse is correct before soldering in the connections
