B&M Quicksilver Off a Gear

I have a Quicksilver installed in my car, it was in the car 10 years ago when I got it. I am finally getting around to hooking up the NSS and reverse lights. It appears that the shifter is off 1 gear though. Everything functions just fine between the shifter and trans, but my reverse lights come on when the trans is in neutral now (shifter is in reverse), and the NSS is off a gear as well. I also noticed that it enters ratchet mode in 2nd gear, instead of drive, I always assumed 2nd gear was correct.

Reading the instructions for a Quicksilver, there is supposed to be a couple pins installed to run this on a 3 speed trans to lockout 4th gear. Mine doesn't seem to have the holes in the shifter base to install these pins. Can I assume that I can just fix this by adjusting the cable differently, or do I need to find a way to lock it out of 4th gear?
